Walkthrough

The pull request modifies the splitChunks function in the core generation module, adjusting the default parameters for chunk size and bleed. The default chunk size has been increased from 512 to 1500, and the bleed parameter has been expanded from 20 to 100. These changes impact how text content is segmented, allowing for larger chunks with increased overlap between them.

🪧 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.

1351-1352: Increased chunk size and overlap for better context preservation.

The changes to increase the default chunk size (512→1500) and bleed/overlap (20→100) should improve context retention during text segmentation, particularly beneficial for RAG operations.

Consider adding a comment explaining the rationale behind these specific values to help future maintainers understand the trade-offs between chunk size, overlap, and memory usage.
