Walkthrough

The pull request restructures the project’s metrics-related code by updating numerous import paths from ai.chronon.online to ai.chronon.online.metrics. Additionally, a new Scala library (metrics_lib) has been introduced, and dependencies have been updated in several BUILD files. Package declarations in key files have also been modified to reflect the reorganization, with no changes affecting the actual runtime functionality.

Poem

In a code maze so vast and neat,
Imports are reformed, oh so sweet.
Metrics now call a brand new home,
With metrics_lib they freely roam.
Cheers to clarity, a refactor treat!

🪧 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>, please review it.
    • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @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.

  • @coderabbitai summary to regenerate the summary of the PR.
  • @coderabbitai resolve resolve all the CodeRabbit review comments.
  • @coderabbitai plan to trigger planning for file edits and PR creation.
  • @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
  • @coderabbitai help to get help.

Other keywords and placeholders

  • Add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.
  • Add @coderabbitai summary to generate the high-level summary at a specific location in the PR description.
  • Add @coderabbitai anywhere in the PR title to generate the title automatically.

This is used by TTLCache which in turn is used by the Metrics API, so unfortunately this is the simplest way to do the refactor right now. Agree this might live elsewhere, maybe a utils online module that is also slimmer. I will keep here for now and move in a future refactor.
