🪧 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.

@fengys1996 Please also take a look at this PR, aiming to provide a new relaxed runtime to constrain CPU usage of spawned tasks.

[fengys1996]

It looks like there are some conflicts and some compilation errors. Please resolve them first.

Do we have a document to describe how this runtime works and how to find a proper priority for the runtime? I'd suggest providing more docs in the runtime crate.

LGTM. There are some remaining enhancements we can acheive in other PRs. e.g. Making tokens of different priorities configurable.

@fengys1996 I think we can test this feature on the new version of GreptimeDB edge now to see if it can manage the total CPU usage.

Great work! Thanks a lot.
