Walkthrough

The changes introduce indexing for the latest_state attribute and add a polymorphic association for statusable_id and statusable_type within the ProcessStatus class in the app/models/transmittable/process_status.rb file. These modifications aim to improve query performance and flexibility in associating the status with various models.

Sequence Diagram(s)

Since the changes involve schema modifications and indexing, a sequence diagram is not necessary for this update.

Poem

In ProcessStatus, where the code does grow,
An index for latest_state now does glow.
Polymorphic links, oh what a twist,
Flexibly binding, can't be missed!
Performance soars as queries fly high,
With these changes, efficiency touches the sky.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

16-17: LGTM! But verify the index creation in the database.

The index on latest_state is a good addition to optimize query performance.

Ensure that the index has been successfully created in the database.

The index on statusable_id and statusable_type is a good addition to optimize query performance for the polymorphic association.

Ensure that the index has been successfully created in the database.
