Walkthrough

The modifications to the search function in the caching module enhance query handling by introducing the option to incorporate a VRL function into the hashing process. This improvement allows for a more dynamic approach to querying, where the hash is computed using both the original SQL and the VRL function if available. The changes streamline the control flow while maintaining the overall structure of the function, ultimately enhancing caching efficiency and query processing.

Changes

Files Change Summary
src/service/search/cache/mod.rs Updated the hashing logic in the search function to incorporate an optional VRL function, improving query handling and caching. Moved initialization of req within the function.

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.

76-81: Ensure proper decoding of query_fn.

The query_fn is being decoded using base64::decode_url. Ensure that the query_fn is always URL-safe base64 encoded.


84-88: LGTM! But verify the hash computation logic.

The hash computation logic now includes query_fn if it exists. Ensure that this change does not introduce any collisions or performance issues.
