Walkthrough

The ResponseInfo struct in the codebase was updated to include a new string field, ResponseBody, to store the subgraph response body. The constructor function newResponseInfo was modified to initialize this field with the string value of res.out. No other logic or control flow was altered.

Changes

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.
  • Explain this complex logic.
  • 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 explain this code block.
  • @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 explain its main purpose.
  • @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.

Support

58-60: Potential memory-/privacy bloat: copying entire response into an immutable string

ResponseBody duplicates the whole sub-graph payload (bytes.Buffer → string).
On large responses this might incur a noticeable extra allocation & GC pressure and, depending on what your LoaderHooks do, may accidentally leak PII if the struct is simply logged.

If you only need the body for debugging/metrics consider:

• keeping it as []byte and letting hooks opt-in to a copy (clone()),
• or truncating / redacting the payload before assigning.

Not blocking, but worth evaluating usage patterns.
