Walkthrough

The codebase has undergone significant updates, primarily transitioning from the github.com/go-redis/redis package to github.com/redis/go-redis, reflecting an upgrade to version 9. This change necessitated modifications in import paths, function signatures, and instantiation methods across multiple files. Additionally, several struct field names have been changed to follow Go's convention for exported fields, enhancing visibility and accessibility. The overall structure and organization of the code have been improved through refactoring.

Changes

🐇 "In the garden where I hop and play,
New paths of code have come my way.
With Redis fresh and fields so bright,
I dance with joy, oh what a sight!
Each change a hop, each fix a leap,
In this code world, my heart will keep!" 🐇

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.
