  1. content_subtype (integer)
  2. authority (string)

These additions provide more control over gRPC client behavior, potentially improving flexibility in communication protocols and routing.

Please add a description for the content_subtype property to maintain consistency with other properties and provide clarity on its purpose and usage.


3681-3692: Approved: New gRPC client dial options for retry and timeout control

Two valuable gRPC client dial options have been added:

  1. disable_retry: Allows disabling the retry mechanism.
  2. idle_timeout: Enables setting a timeout for idle connections.

These additions provide more fine-grained control over client behavior, potentially improving reliability and resource management.

Consider updating the project's documentation to explain the implications of disabling retries and setting idle timeouts, including best practices and potential use cases for these options.


3730-3737: Approved: Added max_call_attempts and max_header_list_size options

Two new gRPC client dial options have been introduced:

  1. max_call_attempts: Limits the number of call attempts.
  2. max_header_list_size: Sets a maximum size for the header list.

These additions enhance control over client behavior and can help prevent excessive resource usage and potential security issues.

3855-3866: Approved: New gRPC client dial options for write buffer and user agent

Two new gRPC client dial options have been added:

  1. shared_write_buffer: Enables or disables write buffer sharing.
  2. user_agent: Allows setting a custom user agent string.

These additions provide more control over client behavior and identification, potentially improving performance and debugging capabilities.

Consider updating the project's documentation to explain the performance implications of shared write buffers and best practices for setting custom user agent strings, including any formatting guidelines or conventions.


6978-6985: Approved with suggestion: Consistent addition of gRPC client dial options

This segment duplicates the content_subtype and authority options in another part of the configuration schema, maintaining consistency across different sections.

As noted in a previous comment, please add a description for the content_subtype property to maintain consistency with other properties and provide clarity on its purpose and usage.


7333-7340: Approved with suggestion: Consistent addition of gRPC client dial options

This suggestion has been made multiple times, and it would be beneficial to address it across all instances of this property.

internal/net/grpc/health/health.go (1)

29-35: Approve logic changes with a suggestion for error handling.

The updated implementation is more robust and flexible, automatically registering all services and improving observability through logging. The overall health status setting is a good addition.

Consider adding error handling for the SetServingStatus calls. While these operations are unlikely to fail, it's a good practice to handle potential errors. Here's a suggested improvement:

 func Register(srv *grpc.Server) {
 	hsrv := health.NewServer()
 	healthpb.RegisterHealthServer(srv, hsrv)
 	for api := range srv.GetServiceInfo() {
-		hsrv.SetServingStatus(api, healthpb.HealthCheckResponse_SERVING)
+		if err := hsrv.SetServingStatus(api, healthpb.HealthCheckResponse_SERVING); err != nil {
+			log.Error("failed to set serving status for service: " + api, err)
+		}
 		log.Debug("gRPC health check server registered for service:\t" + api)
 	}
-	hsrv.SetServingStatus("", healthpb.HealthCheckResponse_SERVING)
+	if err := hsrv.SetServingStatus("", healthpb.HealthCheckResponse_SERVING); err != nil {
+		log.Error("failed to set overall serving status", err)
+	}
 }

This change adds error handling and logging for potential failures in setting the serving status.

internal/net/grpc/health/health_test.go (2)

36-36: LGTM: Struct simplification aligns with updated function signature.

The simplification of the args struct to only include the srv *grpc.Server field is appropriate and consistent with the changes to the Register function signature.

Consider adding a brief comment above the args struct to explain its purpose in the test, e.g.:

// args represents the input parameters for the Register function
type args struct {
    srv *grpc.Server
}

59-59: LGTM: Improved service registration check.

The use of healthpb.Health_ServiceDesc.ServiceName instead of a hardcoded string is an excellent improvement. It makes the test more robust and less prone to breaking if the service name changes in the future.

For improved clarity, consider adding a brief comment explaining the purpose of this check:

// Verify that the health check server has been registered with the gRPC server
if _, ok := srv.GetServiceInfo()[healthpb.Health_ServiceDesc.ServiceName]; !ok {
    return errors.New("health check server not registered")
}
dockers/tools/benchmark/operator/Dockerfile (1)

87-87: Approve with suggestion: Consider parameterizing the config file.

The addition of a default configuration file is a good practice and aligns with the PR objectives. However, using a sample configuration in a production image might not be ideal for all use cases.

Consider parameterizing the config file path using a build argument. This would allow users to specify a custom config file at build time. Here's an example of how you could modify this:

+ ARG CONFIG_FILE=cmd/tools/benchmark/operator/sample.yaml
- COPY cmd/tools/benchmark/operator/sample.yaml /etc/server/config.yaml
+ COPY ${CONFIG_FILE} /etc/server/config.yaml

This change would maintain the current behavior by default while providing flexibility for different environments or use cases.

dockers/tools/benchmark/job/Dockerfile (1)

95-95: LGTM: Good addition of a default configuration file.

Adding a default configuration file is a good practice. It provides a starting point for users and ensures the container has a working configuration out of the box.

Consider adding a comment above this line to explain the purpose of this configuration file, e.g.:

# Copy default configuration file
COPY cmd/tools/benchmark/job/sample.yaml /etc/server/config.yaml
dockers/ci/base/Dockerfile (2)

48-48: LGTM! Consider adding a comment for clarity.

The addition of the RUSTUP_HOME environment variable is a good practice for explicitly defining the Rust toolchain installation path. This aligns well with the PR objectives of enhancing configurations.

Consider adding a comment explaining the purpose of this variable for better maintainability:

+# Set RUSTUP_HOME to define Rust toolchain installation path
ENV RUSTUP_HOME=${RUST_HOME}/rustup

Line range hint 1-130: Consider documenting the Dockerfile structure and exploring multi-stage builds.

While the changes made are appropriate, the overall complexity of this Dockerfile suggests that some additional documentation might be beneficial. Consider adding comments to explain the purpose of different sections or groups of installations.

Additionally, given the number of tools and languages being installed, you might want to explore using multi-stage builds to optimize the final image size. This could potentially improve build times and reduce the attack surface of the resulting container.

dockers/dev/Dockerfile (1)

Line range hint 1-148: Consider using a non-root user and adding a security scan step

The Dockerfile is well-structured and efficiently uses multi-stage builds and caching mechanisms. However, there are two areas for potential improvement:

  1. Security: The container is currently set to run as root (line 148). While this is sometimes necessary for development environments, it's generally a good practice to use a non-root user when possible. Consider adding a non-root user and switching to it at the end of the Dockerfile.

  2. Security Scanning: Given the complexity of this development environment, it would be beneficial to add a security scanning step to check for vulnerabilities in the installed packages.

Here's a suggestion to address these points:

# At the beginning of the file, after the FROM instruction
+ARG USERNAME=vscode
+ARG USER_UID=1000
+ARG USER_GID=$USER_UID

# At the end of the file, replace the last line with:
-USER root:root
+RUN groupadd --gid $USER_GID $USERNAME \
+    && useradd --uid $USER_UID --gid $USER_GID -m $USERNAME \
+    && apt-get update \
+    && apt-get install -y sudo \
+    && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME \
+    && chmod 0440 /etc/sudoers.d/$USERNAME
+
+# Install Trivy for vulnerability scanning
+RUN curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin v0.18.3
+
+# Run Trivy vulnerability scanner
+RUN trivy filesystem --exit-code 1 --severity HIGH,CRITICAL /
+
+USER $USERNAME

# Consider adding a .trivyignore file to the project root if there are known issues that can't be immediately addressed

This change adds a non-root user, installs and runs Trivy for vulnerability scanning, and switches to the non-root user at the end. Adjust the USERNAME, USER_UID, and USER_GID as needed for your project.

internal/net/grpc/server.go (4)

121-125: LGTM: NumStreamWorkers implementation with a minor suggestion

The NumStreamWorkers function is correctly implemented as a wrapper around grpc.NumStreamWorkers. The implementation, parameter, and return types are correct.

The comment is informative, but could be slightly improved for clarity:

Consider updating the comment to:

// NumStreamWorkers returns a ServerOption that sets the number of worker goroutines for processing incoming streams.
// Setting this to zero (default) disables workers and spawns a new goroutine for each stream.

This minor change makes the comment more concise and easier to read.


127-131: LGTM: SharedWriteBuffer implementation with a suggestion for the comment

The SharedWriteBuffer function is correctly implemented as a wrapper around grpc.SharedWriteBuffer. The implementation, parameter, and return types are accurate.

However, the comment could be more concise:

Consider updating the comment to:

// SharedWriteBuffer returns a ServerOption that enables reusing the per-connection transport write buffer.
// When set to true, each connection will release the buffer after flushing data to the network.

This change makes the comment more concise while retaining all necessary information.


133-137: LGTM: WaitForHandlers implementation with a suggestion for the comment

The WaitForHandlers function is correctly implemented as a wrapper around grpc.WaitForHandlers. The implementation, parameter, and return types are accurate.

The comment is informative but could be more concise:

Consider updating the comment to:

// WaitForHandlers returns a ServerOption that configures the Stop method to wait for all outstanding
// method handlers to exit before returning. By default, Stop returns immediately after closing connections.

This change makes the comment more concise while retaining all necessary information.


139-178: LGTM: Comprehensive API reference comment with formatting suggestions

The API reference comment block provides valuable information about the status of various gRPC server APIs in this package. It's well-organized into categories and includes a link to the official documentation.

To improve readability, consider the following formatting suggestions:

  1. Use consistent formatting for each API entry:

    // - FunctionName: Brief description
  2. Add a brief description for each category:

    // 1. Already Implemented APIs
    //    These APIs are currently implemented in this package.
    
    // 2. Unnecessary for this package APIs
    //    These APIs are not needed for the current implementation.
    
    // 3. Experimental APIs
    //    These APIs are experimental and may change in future gRPC versions.
    
    // 4. Deprecated APIs
    //    These APIs are deprecated and should not be used in new code.
  3. Consider using godoc-style comments for better integration with Go documentation tools:

    // API References: https://pkg.go.dev/google.golang.org/grpc#ServerOption
    //
    // 1. Already Implemented APIs
    //    These APIs are currently implemented in this package.
    //    - ConnectionTimeout: Sets the timeout for connection establishment
    //    - Creds: Sets credentials for server connections
    //    ...

These changes will make the comment block more consistent and easier to read while maintaining its informative nature.

k8s/discoverer/configmap.yaml (3)

45-45: LGTM: Channelz enabled for improved monitoring

The addition of enable_channelz: true is a good choice for enhancing observability. This feature will provide detailed runtime statistics and debugging information for the gRPC server.

Consider updating the project documentation to mention this new monitoring capability and provide guidance on how to access and interpret Channelz data.


64-64: Consider explicitly setting num_stream_workers

Setting num_stream_workers: 0 likely means the system will use a default value or auto-configure. While this can work, explicit configuration might provide more predictable performance.

Consider setting an explicit value based on your system's resources. For example:

num_stream_workers: 4  # Adjust based on your CPU cores and expected workload

This will give you more control over resource allocation and potentially improve performance predictability.


Line range hint 45-67: Summary of gRPC server configuration changes

The new configuration options added to the gRPC server settings provide enhanced control over server behavior and potentially improve performance. Here's a summary of the changes and their implications:

  1. Channelz is enabled, improving observability.
  2. No limit on concurrent streams, which may need adjustment to prevent resource exhaustion.
  3. Stream workers are set to auto-configure, but explicit setting might be beneficial.
  4. Shared write buffer is disabled, potentially improving performance but may increase memory usage.
  5. The server will wait for handlers during shutdown, improving reliability but potentially increasing shutdown time.

These changes offer more fine-grained control over the gRPC server's behavior. To ensure optimal performance and stability:

  1. Implement comprehensive monitoring for resource usage, especially memory and CPU.
  2. Set up alerts for abnormal resource consumption or extended shutdown times.
  3. Conduct load testing to verify the impact of these changes under various scenarios.
  4. Consider creating a runbook for tuning these parameters based on observed performance metrics.

By carefully monitoring and adjusting these settings as needed, you can optimize the performance and reliability of your Vald discoverer component.

k8s/manager/index/configmap.yaml (5)

45-45: LGTM: New gRPC server options enhance configurability

The new gRPC server options (enable_channelz, max_concurrent_streams, num_stream_workers, shared_write_buffer, and wait_for_handlers) provide more granular control over server behavior and performance. These additions align with the PR objectives to enhance gRPC configurations.

Consider updating the project documentation to explain these new options, their default values, and their impact on server performance and behavior.

Also applies to: 60-60, 64-64, 66-67


272-272: LGTM: Enhanced gRPC client options for discoverer

The new gRPC client options (content_subtype, authority, disable_retry, idle_timeout, max_call_attempts, and max_header_list_size) in the discoverer section provide more granular control over client behavior and connection management. These additions align with the PR objectives to improve gRPC configurations.

Consider updating the project documentation to explain these new options, their default values, and their impact on client behavior and performance. Additionally, it might be helpful to provide guidelines on when and how to adjust these values based on different deployment scenarios.

Also applies to: 278-283, 285-285, 294-295


324-326: LGTM: Additional dial options for discoverer

The new dial options (shared_write_buffer and user_agent) provide additional control over connection behavior. The shared_write_buffer option may improve performance, while the user_agent option allows for custom identification of the client.

Consider updating the project documentation to explain these new options, their default values, and their potential impact on performance and debugging. For the user_agent option, it might be helpful to provide guidelines on how to set a meaningful value that aids in request tracing and debugging.


358-358: LGTM: Consistent gRPC client option for agent

The addition of the content_subtype option in the agent_client_options section provides consistency with the discoverer client configuration. This change aligns with the PR objectives to improve gRPC configurations across different components.

Ensure that the project documentation is updated to explain this new option, its default value, and its potential use cases in the context of agent client communication.


Line range hint 1-458: Summary: Comprehensive gRPC configuration enhancements

The changes in this ConfigMap file significantly enhance the gRPC configuration options for both server and client components. These additions provide more granular control over various aspects of gRPC communication, including performance, resource management, and connection behavior. The changes are consistent across different components (server, discoverer, and agent client), which should lead to a more uniform and manageable configuration approach.

Consider the following recommendations:

  1. Develop a comprehensive guide on tuning these new gRPC options for different deployment scenarios and workloads.
  2. Implement monitoring and alerting for key metrics related to these new options (e.g., concurrent streams, idle connections) to help operators optimize configurations.
  3. Consider creating pre-set configuration profiles (e.g., high-performance, low-latency, resource-constrained) that users can easily apply based on their needs.
  4. Ensure that the default values chosen for these new options provide a good balance between performance and resource usage for most common deployment scenarios.
k8s/gateway/gateway/lb/configmap.yaml (4)

45-45: LGTM: New gRPC server options enhance configurability

The new gRPC server options (enable_channelz, max_concurrent_streams, num_stream_workers, shared_write_buffer, and wait_for_handlers) provide more granular control over server behavior and performance. These additions align well with the PR objectives of enhancing gRPC configurations.

Consider updating the project documentation to explain these new options, their default values, and their impact on server performance and behavior.

Also applies to: 60-60, 64-64, 66-67


274-274: LGTM: Enhanced gRPC call options

The addition of content_subtype and user_agent in the call_option section provides more control over gRPC call metadata. Setting the user agent to "Vald-gRPC" is a good practice for identification and debugging purposes.

Consider making the user_agent value configurable, allowing users to set custom user agents if needed. This could be useful for tracking different client versions or deployments.

Also applies to: 328-328


280-280: LGTM: Comprehensive gRPC dial options added

The new dial options (authority, disable_retry, idle_timeout, max_call_attempts, max_header_list_size, shared_write_buffer, and user_agent) provide fine-grained control over gRPC connection behavior and retry logic. These additions align well with the PR objectives of enhancing gRPC configurations.

  1. Consider updating the project documentation to explain these new options, their default values, and their impact on connection behavior and performance.
  2. The idle_timeout is set to 1h, which seems reasonable. However, you might want to make this configurable or adjust based on your specific use case and expected traffic patterns.
  3. As mentioned earlier, consider making the user_agent value configurable.

Also applies to: 285-287, 296-297, 326-326, 328-328


360-360: LGTM: Consistent gRPC options for agent clients

The changes made to call_option and dial_option in the agent_client_options section mirror those made in the gateway configuration. This ensures consistency in gRPC behavior across different components of the system.

For consistency and maintainability, consider extracting common gRPC options into a shared configuration section that can be referenced by both gateway and agent client configurations. This would reduce duplication and make it easier to manage these settings in the future.

Also applies to: 366-366, 371-373, 382-383, 412-412, 414-414

k8s/index/job/correction/configmap.yaml (3)

Line range hint 45-67: LGTM. Consider documenting parameter choices.

The new gRPC server parameters enhance debugging capabilities and performance control. The changes look good, but I suggest documenting the reasoning behind setting max_concurrent_streams and num_stream_workers to 0, as well as the choice of shared_write_buffer: false. This documentation will help future maintainers understand the performance implications of these settings.


274-280: LGTM. Document implications of new call options.

The new gRPC call options content_subtype and max_call_attempts provide more granular control over gRPC calls. However, it would be beneficial to document the implications of leaving content_subtype empty and setting max_call_attempts to 0. This will help other developers understand the expected behavior and any potential impact on the system.


Line range hint 280-328: LGTM. Consider documenting dial option choices.

The new gRPC dial options provide enhanced control over connection behavior. The changes look good, particularly the setting of user_agent to "Vald-gRPC" for better client identification. However, I recommend documenting the reasoning behind leaving authority empty and setting max_header_list_size to 0. Also, explain the choice of a 1-hour idle_timeout and why shared_write_buffer is set to false. This documentation will help maintain consistency across the project and assist future developers in understanding these configuration choices.

Makefile (1)

393-413: New target added to set correct permissions

The new perm target is a useful addition to the Makefile. It sets the correct permissions for directories and files in the project, which is important for security and consistency. Here's a breakdown of what it does:

  1. Sets 755 permissions for all directories (except .git)
  2. Sets 644 permissions for all files (except .git and .gitignore)
  3. Sets specific permissions for the .git directory and its contents
  4. Sets 644 permissions for .gitignore and .gitattributes files

This is a good practice for maintaining consistent file permissions across the project.

Consider adding this target to your CI/CD pipeline or as a pre-commit hook to ensure consistent permissions are maintained throughout the development process.

internal/net/grpc/option.go (6)

258-259: Simplify the nil check when initializing g.copts

In multiple functions, the condition if g.copts == nil && cap(g.copts) == 0 can be simplified to if g.copts == nil. A nil slice in Go already has a capacity of zero, so the additional capacity check is redundant.

Also applies to: 268-269, 279-280, 291-292, 301-302


401-402: Simplify the nil check when initializing g.dopts

In functions like WithInitialWindowSize and WithInitialConnectionWindowSize, the condition if g.dopts == nil && cap(g.dopts) == 0 can be simplified to if g.dopts == nil. Since a nil slice has zero capacity, the capacity check is unnecessary.

Also applies to: 414-415


552-556: Improve error logging for invalid durations

When logging invalid durations, using %d with time.Duration displays the value in nanoseconds, which may not be clear. Consider using %v or formatting the duration for better readability.

Apply this change:

-	log.Errorf("invalid idle timeout duration: %d", d)
+	log.Errorf("invalid idle timeout duration: %v", d)

375-376: Simplify the nil check when initializing g.dopts

The condition if g.dopts == nil && cap(g.dopts) == 0 can be simplified to if g.dopts == nil in functions like WithWriteBufferSize, WithReadBufferSize, and WithMaxMsgSize. The capacity check is redundant when the slice is nil.

Also applies to: 388-389, 428-429


540-541: Redundant condition in WithDisableRetry

In WithDisableRetry, the function checks if disable before appending grpc.WithDisableRetry(). Since grpc.WithDisableRetry() disables retries unconditionally, you can simplify the function by always appending the option if the intention is to disable retries when disable is true.


Line range hint 622-642: Handle default case in WithClientInterceptors

In the WithClientInterceptors function, the default case in the switch statement is empty. Consider adding a log or comment to handle unexpected interceptor names, which can aid in debugging.

internal/net/grpc/client.go (1)

149-151: Simplify the condition by removing the nil check on the slice.

In Go, a nil slice has a length of zero. Therefore, checking g.copts != nil is redundant. You can simplify the condition as follows:

-if g.copts != nil && len(g.copts) != 0 {
+if len(g.copts) != 0 {
internal/config/server_test.go (1)

Discrepancy in server.Option Count for GRPC Mode

The test expects 31 server.Options when Mode is GRPC, but the Opts method is returning 47. Please verify whether the additional 16 options are intentional additions or if they indicate an issue that needs to be addressed.

internal/net/grpc/health/health.go (2)

21-24: LGTM: Import changes enhance functionality and readability.

The addition of the log package and the use of the healthpb alias for grpc_health_v1 are appropriate changes that support the new functionality and improve code readability.


28-28: Approve signature change, but verify impact on existing code.

The simplified function signature aligns well with the new implementation that dynamically registers all services. However, this change may impact existing code that calls this function.

Please run the following script to check for any calls to the old Register function that might need updating:

internal/db/rdb/mysql/dbr/dbr.go (1)

62-68: 🛠️ Refactor suggestion

Consider renaming and documenting the function for clarity

The function name prepareSelect doesn't clearly convey its purpose of converting a slice to a slice of empty interfaces. Consider renaming it to something more descriptive, such as toInterfaceSlice or convertToAnySlice.

Additionally, add a comment explaining the function's purpose and usage to improve code readability and maintainability.

Simplify implementation using append

The current implementation can be simplified using the append function, which may be more idiomatic in Go. Here's an alternative implementation:

-func prepareSelect[T any](a ...T) (b []any) {
-	b = make([]any, len(a))
-	for i := range a {
-		b[i] = a[i]
-	}
-	return b
+func prepareSelect[T any](a ...T) []any {
+	return append(make([]any, 0, len(a)), a...)
+}

This implementation preallocates the slice capacity for efficiency and uses append to add all elements at once.

Be cautious of type safety implications

While this function provides flexibility, be aware that converting to []any loses type information. Ensure that the calling code handles type assertions or type switches carefully to maintain type safety.

To verify the usage and potential type safety issues, you can run the following script:

This script will help identify where prepareSelect is used and how the resulting []any is handled in the codebase.

✅ Verification successful

Usage of prepareSelect is correct and type-safe

The prepareSelect function is used appropriately in the internal/db/rdb/mysql/dbr package for preparing arguments for SQL queries. Its usage is limited to the Select method of both session and tx structs. The function's implementation using generics ensures type safety during the conversion to []interface{}, which is a common requirement for SQL operations.

No type assertions or unsafe type switches related to prepareSelect were found in the codebase, indicating that the resulting []interface{} is likely used directly in SQL operations as intended.

While the suggestion to rename the function for clarity and using append for a more idiomatic implementation are still valid, there are no apparent type safety issues introduced by the current implementation or usage of prepareSelect.

internal/db/rdb/mysql/dbr/session.go (2)

Line range hint 1-78: Overall assessment of changes in session.go

The modification to the Select method is the only change in this file. The introduction of prepareSelect potentially impacts all SELECT queries, but the unchanged method signature maintains backward compatibility. The rest of the file, including other crucial methods like Begin, Close, and PingContext, remain unaltered.

To ensure the reliability of this change:

  1. Verify that the prepareSelect function correctly handles all possible input scenarios.
  2. Update unit tests for the Select method to cover various column input cases.
  3. Perform integration tests to ensure that existing queries using this Select method still function as expected.

To further validate the impact of this change, please run the following script:

#!/bin/bash
# Description: Find test files related to the Select method and prepareSelect function

echo "Test files potentially affected by the Select method change:"
rg --type go "func Test.*Select" --files-with-matches

echo "\nTest files that might need updating for prepareSelect:"
rg --type go "prepareSelect" --files-with-matches -g '*_test.go'

This will help identify test files that may need updating to cover the new prepareSelect functionality.


45-45: Review the impact of prepareSelect on SELECT queries

The introduction of prepareSelect(column...) alters how columns are processed before being passed to the underlying Select method. This change could have significant implications for all SELECT queries in the system.

  1. Could you provide more information about the prepareSelect function? Understanding its purpose and implementation would help in assessing the full impact of this change.

  2. Consider adding a comment to explain why this preprocessing step was introduced. This would help future maintainers understand the rationale behind the change.

  3. Ensure thorough testing of various SELECT queries to verify that this change doesn't introduce any unexpected behavior, especially with complex queries or edge cases.

To help verify the impact and usage of this new prepareSelect function, please run the following script:

This will help us understand the implementation of prepareSelect and identify if it's used consistently across the codebase.

56-56: LGTM: Test case setup correctly updated.

The removal of the name field from the test case setup is consistent with the changes to the args struct and the Register function signature. This change appropriately focuses the test on the server registration functionality.


Line range hint 1-89: Overall, the changes improve test quality and consistency.

The modifications to this test file are well-aligned with the updated Register function signature. They simplify the test setup, improve robustness by using the official service descriptor, and maintain consistency throughout the file. These changes contribute to a more maintainable and reliable test suite for the health check functionality.


83-83: LGTM: Register function call updated correctly.

The Register function call has been appropriately updated to only pass the srv argument, which is consistent with the changes to the function signature.

To ensure full consistency, let's verify the actual Register function implementation:

✅ Verification successful

The MaxConcurrentStreams function is correctly implemented as a wrapper around grpc.MaxConcurrentStreams. It maintains the correct parameter and return types, adhering to the gRPC naming convention and functionality.

k8s/agent/ngt/configmap.yaml (1)

Line range hint 45-67: Review of new gRPC server configuration options

The new gRPC server configuration options enhance the server's capabilities and align with the PR objectives. Here's a breakdown of the changes:

  1. enable_channelz: true (line 45): This is good for improving observability of gRPC channels.
  2. max_concurrent_streams: 0 (line 60): This allows unlimited concurrent streams, which could potentially lead to resource exhaustion under high load.
  3. num_stream_workers: 0 (line 64): This uses the default number of stream workers, which is generally safe but may not be optimal for all scenarios.
  4. shared_write_buffer: false (line 66): This can potentially improve performance by giving each stream its own write buffer, at the cost of increased memory usage.
  5. wait_for_handlers: true (line 67): This is good for ensuring graceful shutdowns.

These settings generally improve the gRPC server's configuration. However, I recommend verifying the impact of setting max_concurrent_streams to 0 (unlimited) in your specific use case. Consider setting a reasonable limit to prevent potential resource exhaustion under high load.

To help verify the impact, you can run the following command to check for any other occurrences of max_concurrent_streams in the codebase:

This will help ensure consistency across the configuration and identify any potential conflicts or overrides.

✅ Verification successful

Configuration Consistency Verified

The max_concurrent_streams: 0 setting is consistently applied across the codebase in all relevant configmap files and Helm charts. This indicates an intentional configuration choice to allow unlimited concurrent streams. Given the widespread adoption, the setting is appropriate and aligns with the project's scalability and resource management strategies.

k8s/discoverer/configmap.yaml (2)

66-66: LGTM: Disabled shared write buffer for potential performance improvement

Setting shared_write_buffer: false is a reasonable choice. This configuration means each stream will have its own buffer, which can reduce contention and potentially improve performance.

Monitor the memory usage of your gRPC server after deploying this change. If you notice significant increases in memory consumption, you may need to reconsider this setting or adjust your resource allocation.


67-67: LGTM: Enabled waiting for handlers during shutdown

Setting wait_for_handlers: true is a good choice for improving reliability during server shutdown. This ensures that all ongoing requests are properly handled before the server stops.

Monitor the shutdown behavior of your gRPC server after deploying this change. If you notice significantly increased shutdown times, you may need to:

  1. Adjust your deployment strategy to account for longer shutdown periods.
  2. Implement a timeout mechanism for long-running handlers to prevent excessively long shutdowns.

Consider logging the shutdown duration to track this metric over time.

k8s/gateway/gateway/mirror/configmap.yaml (3)

28-28: LGTM: New gRPC server configuration options added.

The new gRPC server configuration options (enable_channelz, num_stream_workers, shared_write_buffer, and wait_for_handlers) have been successfully added, aligning with the PR objectives. These additions enhance the server's configurability and performance management capabilities.

Please ensure that these new settings align with your performance requirements and use cases:

  1. enable_channelz: true - This enables gRPC's channelz service, which can be useful for debugging but may have a slight performance impact.
  2. num_stream_workers: 0 - This setting uses the default number of workers. Consider adjusting if you have specific concurrency requirements.
  3. shared_write_buffer: false - This uses separate write buffers per stream, which can be beneficial for performance in some scenarios.
  4. wait_for_handlers: true - This ensures all handlers are ready before serving, which can improve reliability during startup.

28-28: LGTM: TCP_CORK enabled for metrics server.

The tcp_cork option has been enabled for the metrics server, which can potentially improve network efficiency by coalescing small writes.

Please verify that enabling TCP_CORK doesn't negatively impact the responsiveness of the metrics server, especially for time-sensitive metrics. Consider monitoring the following after deployment:

  1. Latency of metric retrieval
  2. CPU usage of the metrics server
  3. Network efficiency (e.g., number of packets sent)

If you notice any degradation in performance or responsiveness, you may want to reconsider this setting.


28-28: LGTM with suggestions: New gRPC client configuration options added.

The new gRPC client configuration options (authority, max_call_attempts, and user_agent) have been successfully added, aligning with the PR objectives. These additions provide more control over the client's behavior.

Please address the following points:

  1. authority: "" - Clarify the purpose of leaving this empty. Is it intentional to use the default authority?

  2. max_call_attempts: 0 - This setting might indicate unlimited retry attempts, which could potentially lead to issues in case of persistent failures. Consider setting a reasonable upper limit to prevent excessive resource consumption.

  3. user_agent: Vald-gRPC - This is a good addition for identification. Ensure this user agent string is consistent across all Vald components for easier debugging and monitoring.

Additionally, please verify that these new client settings work as expected in your testing environment, particularly focusing on the retry behavior and any impact on performance or resource usage.

k8s/index/job/save/configmap.yaml (4)

45-45: New gRPC server options added

The following new gRPC server options have been added:

  • enable_channelz: true: This enables the gRPC channelz service, which can be useful for debugging and monitoring gRPC internals.
  • max_concurrent_streams: 0: This uses the default value (no explicit limit on concurrent streams).
  • num_stream_workers: 0: This likely uses the default value for stream workers.
  • shared_write_buffer: false: This is generally the default and safer option, preventing shared write buffers across streams.
  • wait_for_handlers: true: This ensures all handlers are ready before the server starts serving requests.

These additions provide more fine-grained control over the gRPC server behavior and can help with debugging and performance tuning.

To ensure these new options are properly recognized and applied, please verify that the gRPC server initialization code in the application correctly reads and applies these configuration values.

Also applies to: 60-60, 64-67


274-274: New gRPC client options added

Several new gRPC client options have been added to both the discoverer and agent_client_options sections:

  1. content_subtype: "": Uses the default content subtype.
  2. authority: "": Uses the default authority (usually the server's address).
  3. disable_retry: false: Allows retries, which is good for reliability.
  4. idle_timeout: 1h: Sets a 1-hour idle timeout, suitable for long-running services.
  5. max_call_attempts: 0: Likely uses the default value for maximum call attempts.
  6. max_header_list_size: 0: Likely uses the default value for maximum header list size.
  7. user_agent: Vald-gRPC: Sets a custom user agent, which is good for identification in logs and metrics.

These additions provide more control over the gRPC client behavior and can help with debugging, performance tuning, and reliability.

To ensure these new options are correctly applied, please verify that the gRPC client initialization code in the application properly reads and uses these configuration values.

Overall, these changes appear to be a positive enhancement to the Vald project's configurability.

k8s/index/job/creation/configmap.yaml (6)

67-67: Approved: Waiting for handlers improves reliability.

Setting wait_for_handlers: true is a good practice. It ensures that the gRPC server waits for all handlers to be registered before starting, which can prevent issues with early requests to unregistered handlers.

Consider adding a comment to explain this behavior:

wait_for_handlers: true  # Ensure all handlers are registered before the server starts

This setting might slightly increase startup time, but it improves the reliability of your service.


66-66: Monitor the impact of disabling shared write buffer.

Setting shared_write_buffer: false means each stream will have its own write buffer. This can potentially improve performance by reducing contention, but it may also increase memory usage.

Consider monitoring the performance and memory usage of your gRPC server after implementing this change. If you notice significant memory pressure, you might want to reconsider this setting or adjust your server's resources accordingly.

To help monitor the impact, consider setting up metrics for gRPC server memory usage and performance. You can verify if such metrics are already in place by running:

#!/bin/bash
# Check for gRPC server metrics related to memory usage and performance

rg 'grpc.*metrics|memory.*usage|performance.*monitor' --type go

Line range hint 274-329: Review and document critical gRPC client settings.

Several new gRPC client configurations have been added. Pay special attention to these settings:

  1. disable_retry: false (line 285): Ensure this aligns with your error handling and resilience strategy.
  2. idle_timeout: 1h (line 287): Consider if this timeout is appropriate for your use case.
  3. max_call_attempts: 0 (line 296): This sets no limit on call attempts. Consider setting a reasonable limit.
  4. user_agent: Vald-gRPC (line 328): Ensure this user agent string is appropriate and doesn't leak sensitive information.

It's recommended to add comments explaining the reasoning behind these choices, especially for settings that differ from defaults or have significant impact on behavior.

Example:

disable_retry: false  # Retries enabled to improve resilience against transient failures
idle_timeout: 1h  # Long-lived connections to reduce connection establishment overhead
max_call_attempts: 5  # Limit retries to prevent excessive load during outages

To ensure these settings are consistently applied across the project, run:

#!/bin/bash
# Check for consistency in gRPC client settings across the project

rg 'disable_retry|idle_timeout|max_call_attempts|user_agent' --type yaml

Line range hint 360-365: Verify consistency of gRPC client settings across different clients.

The gRPC client settings added here for the agent client options mirror those added earlier for the discoverer client. While consistency is generally good, please verify that these settings are indeed appropriate for both clients:

call_option:
  content_subtype: ""
  max_recv_msg_size: 0
  max_retry_rpc_buffer_size: 0
  max_send_msg_size: 0
  wait_for_ready: true

If the requirements for the agent client differ from the discoverer client, consider adjusting these settings accordingly. If they are intentionally kept the same, consider extracting these common settings into a shared configuration to improve maintainability.

To check for any differences in gRPC client settings between discoverer and agent clients, run:

#!/bin/bash
# Compare gRPC client settings between discoverer and agent clients

echo "Discoverer client settings:"
sed -n '/discoverer:/,/agent_client_options:/p' k8s/index/job/creation/configmap.yaml | grep -E 'call_option:|content_subtype:|max_recv_msg_size:|max_retry_rpc_buffer_size:|max_send_msg_size:|wait_for_ready:'

echo "Agent client settings:"
sed -n '/agent_client_options:/,$p' k8s/index/job/creation/configmap.yaml | grep -E 'call_option:|content_subtype:|max_recv_msg_size:|max_retry_rpc_buffer_size:|max_send_msg_size:|wait_for_ready:'

64-64: Clarify the intended behavior of num_stream_workers: 0.

The setting num_stream_workers: 0 might have different implications depending on the gRPC implementation. It could mean using a default number of workers or enabling auto-scaling. Please clarify the intended behavior and consider adding a comment explaining the choice.

For example:

num_stream_workers: 0  # Use default worker count (or auto-scale, depending on implementation)

This will help future maintainers understand the reasoning behind this configuration.

To verify the behavior, please run the following script:

243-257: ⚠️ Potential issue

Validate numeric fields before setting gRPC dial options

In the Opts() method for DialOption, fields like InitialWindowSize, InitialConnectionWindowSize, MaxHeaderListSize, MaxCallAttempts, etc., are used directly without validation. Setting invalid values (e.g., negative numbers) could cause the gRPC dialer to fail or exhibit unexpected behavior. Consider adding validation to ensure the fields have valid values before applying them.

Apply this diff to add validation checks:

 if g.DialOption != nil {
 	opts = append(opts,
 		grpc.WithAuthority(g.DialOption.Authority),
 		grpc.WithBackoffMaxDelay(g.DialOption.BackoffMaxDelay),
 		grpc.WithClientInterceptors(g.DialOption.Interceptors...),
 		grpc.WithDisableRetry(g.DialOption.DisableRetry),
 		grpc.WithIdleTimeout(g.DialOption.IdleTimeout),
-		grpc.WithInitialConnectionWindowSize(g.DialOption.InitialConnectionWindowSize),
-		grpc.WithInitialWindowSize(g.DialOption.InitialWindowSize),
 		grpc.WithInsecure(g.DialOption.Insecure),
-		grpc.WithMaxCallAttempts(g.DialOption.MaxCallAttempts),
-		grpc.WithMaxHeaderListSize(g.DialOption.MaxHeaderListSize),
-		grpc.WithMaxMsgSize(g.DialOption.MaxMsgSize),
-		grpc.WithReadBufferSize(g.DialOption.ReadBufferSize),
 		grpc.WithSharedWriteBuffer(g.DialOption.SharedWriteBuffer),
 		grpc.WithUserAgent(g.DialOption.UserAgent),
-		grpc.WithWriteBufferSize(g.DialOption.WriteBufferSize),
 	)
+	if g.DialOption.InitialConnectionWindowSize > 0 {
+		opts = append(opts, grpc.WithInitialConnectionWindowSize(g.DialOption.InitialConnectionWindowSize))
+	}
+	if g.DialOption.InitialWindowSize > 0 {
+		opts = append(opts, grpc.WithInitialWindowSize(g.DialOption.InitialWindowSize))
+	}
+	if g.DialOption.MaxCallAttempts > 0 {
+		opts = append(opts, grpc.WithMaxCallAttempts(g.DialOption.MaxCallAttempts))
+	}
+	if g.DialOption.MaxHeaderListSize > 0 {
+		opts = append(opts, grpc.WithMaxHeaderListSize(g.DialOption.MaxHeaderListSize))
+	}
+	if g.DialOption.MaxMsgSize > 0 {
+		opts = append(opts, grpc.WithMaxMsgSize(g.DialOption.MaxMsgSize))
+	}
+	if g.DialOption.ReadBufferSize > 0 {
+		opts = append(opts, grpc.WithReadBufferSize(g.DialOption.ReadBufferSize))
+	}
+	if g.DialOption.WriteBufferSize > 0 {
+		opts = append(opts, grpc.WithWriteBufferSize(g.DialOption.WriteBufferSize))
+	}
 }

Run the following script to ensure all numeric fields are validated:

#!/bin/bash
# Description: Check that all numeric fields in DialOption are conditionally set in Opts()

# List numeric fields in DialOption
rg --type go '^\s+\w+\s+(int|int32|uint32|float64)' internal/config/grpc.go | awk '{print $1}' > numeric_fields.txt

# Compare the lists
echo "Numeric fields not validated before setting options:"
comm -23 <(sort numeric_fields.txt) <(sort validated_fields.txt)

161-168: ⚠️ Potential issue

Ensure all new fields are correctly bound in DialOption.Bind()

While fields like Authority, IdleTimeout, and UserAgent are being processed with GetActualValue, other new string fields such as BackoffBaseDelay and BackoffMaxDelay might also need similar handling to ensure environment variable expansion and proper value assignment.

Apply this diff to bind all string fields consistently:

 func (d *DialOption) Bind() *DialOption {
 	d.Authority = GetActualValue(d.Authority)
 	d.BackoffBaseDelay = GetActualValue(d.BackoffBaseDelay)
+	d.BackoffMaxDelay = GetActualValue(d.BackoffMaxDelay)
 	d.IdleTimeout = GetActualValue(d.IdleTimeout)
 	d.Interceptors = GetActualValues(d.Interceptors)
 	d.MinimumConnectionTimeout = GetActualValue(d.MinimumConnectionTimeout)
 	d.Timeout = GetActualValue(d.Timeout)
 	d.UserAgent = GetActualValue(d.UserAgent)
+	// Bind any additional string fields if necessary
 	return d
 }

Run the following script to check for any string fields in DialOption not processed with GetActualValue:

internal/config/server.go (3)

95-105: New GRPC configuration fields added

The addition of new fields like EnableChannelz, SharedWriteBuffer, WaitForHandlers, and others in the GRPC struct enhances the configurability of the gRPC server. These fields allow for finer control over performance and resource management.


Line range hint 321-325: Clarify the registration logic for EnableChannelz

The condition if s.GRPC.EnableAdmin || s.GRPC.EnableChannelz triggers admin.Register(srv). Ensure that admin.Register(srv) correctly registers the Channelz service when EnableChannelz is true. If admin.Register(srv) does not handle Channelz registration, you should register Channelz separately to achieve the desired functionality.

You can run the following script to verify whether admin.Register(srv) includes Channelz registration:

#!/bin/bash
# Description: Verify if admin.Register(srv) includes Channelz registration.

# Search for the definition of admin.Register function.
rg --type go 'func Register\(srv \*grpc\.Server\)' -A 15 ./internal/net/grpc/admin

# Check if Channelz registration is included within admin.Register.
rg --type go 'channelz.RegisterChannelzServiceToServer\(srv\)' -A 5 ./internal/net/grpc/admin

301-312: Ensure new gRPC server options are correctly set

The new gRPC server options in the Opts function map the GRPC struct fields to server options. Please verify that these options are compatible with your gRPC server implementation and that they are supported in the current version.

🛠️ Refactor suggestion

Refactor to eliminate code duplication in g.dopts initialization

Similar to g.copts, the initialization of g.dopts is repeated in several functions. Consider creating a helper method to initialize g.dopts when it is nil to reduce duplication.

Example refactor:

func (g *gRPCClient) ensureDialOptionsInitialized() {
	if g.dopts == nil {
		g.dopts = make([]grpc.DialOption, 0, defaultDialOptionLength)
	}
}

And update the functions:

+func WithWriteBufferSize(size int) Option {
 	return func(g *gRPCClient) {
 		if size > 1 {
-			if g.dopts == nil && cap(g.dopts) == 0 {

🛠️ Refactor suggestion

Avoid hard-coded magic numbers in test descriptions

The test case name mentions "return 32 grpc.Option", which may need to be updated if the number of options changes in the future. Consider generalizing the test description to avoid hard-coded values.

Apply this diff to update the test name:

-name: "return 32 grpc.Option and nil error when all parameters are set",
+name: "return expected grpc.Options and nil error when all parameters are set",

🛠️ Refactor suggestion

Replace magic number with dynamic length in test expectations

Using make([]grpc.Option, 32) hard-codes the expected number of options, which can make the test brittle. Consider replacing 32 with a length derived from the actual options to improve maintainability.

Apply this diff to calculate the expected length dynamically:

-want: make([]grpc.Option, 32),
+want: make([]grpc.Option, len(actualOptions)),

Make sure to define actualOptions based on the options generated by the configuration to compute the expected length accurately.
