Hi @dackers86 and reviewers,
I'm currently reviewing this pull request and will provide my feedback in a few minutes. In the meantime, I'm providing this summary to help everyone quickly understand the changes and intent.
This pull request, "docs(memorystore): added valkey practical source-code samples", aims to add practical source code samples for Memorystore for Valkey. I've analyzed the changes and here's a breakdown:
Intent: Add new, practical code samples demonstrating various Memorystore for Valkey functionalities.
Changes:
- New README.md (memorystore/valkey/caching/samples/README.md): A new README file was added, providing instructions on prerequisites (Java installation, Memorystore for Valkey instance setup), compiling the code via Maven, and running the sample code. The file is 31 lines long.
- New pom.xml (memorystore/valkey/caching/samples/pom.xml): A new
pom.xmlfile was added, defining project dependencies (Jedis, Google Cloud Client Libraries, and JUnit for testing). The file is 100 lines long. - New Java source code files: Four new Java files were added under
memorystore/valkey/caching/samples/src/main/java/samples/:MemorystoreDeleteItem.java(40 lines): Demonstrates deleting an item from the cache.MemorystoreReadItem.java(37 lines): Demonstrates reading an item from the cache.MemorystoreTTLItem.java(63 lines): Demonstrates caching an item with a Time-To-Live (TTL).MemorystoreWriteItem.java(33 lines): Demonstrates writing an item to the cache.
Checklist: The pull request includes a checklist confirming adherence to the sample format guide, updates to the README, and successful test and lint execution.
I will be checking the code for correctness, style, and adherence to best practices during my review. I'll also verify that the tests pass and that the code is well-documented.
And now, a little haiku to lighten the mood:
Code flows like a stream,
Tests pass, a joyful green light,
Bugs flee in the night.

This pull request adds practical source code samples for Memorystore for Valkey, which is a valuable addition. The samples cover basic operations like writing, reading, deleting, and setting TTL for cached items. The provided README.md is helpful and provides clear instructions.
Here's a summary of the feedback based on the Google Java Style Guide:
- Use descriptive variable names.
- Ensure consistent spacing and indentation.
- Add Javadoc comments for classes and methods.
- Handle potential exceptions.
- Use try-with-resources for resource management.

@dackers86 you need to make sure that all files have the appropriate Apache 2 header please. |

| ### MemoryStore for Valkey Instance | ||
|
|
||
| A working instance of memorystore for valkey must be available. You can run the [Valkey CLI](https://valkey.io/topics/cli/) for a local instance, or create an instance through the [GCP Platform](https://console.cloud.google.com/memorystore/valkey/instances?). |

valkey CLI -> maybe indicate they should use the 'create' command? Or provide a 'local instance' snippet?
| ## Run the sample code | ||
|
|
||
| ```bash | ||
| mvn exec:java -Dexec.mainClass=MemorystoreTTLItem //Replace the main class as needed |

bash comment should be '#' instead of '//'?

populate groupId and artifactdId similar to https://github.com/GoogleCloudPlatform/java-docs-samples/blob/main/memorystore/redis/pom.xml ?

try-with-resources ? this guaranatees proper resource closure.
| jedis.set(itemId, itemValue); | ||

maybe add a 'get' call to confirm it?
… updated pre-requisite descriptions
