Walkthrough

The changes involve modifications to the search functionality across multiple files, primarily focusing on the return types of various functions. The updates introduce an additional integer value representing target partitions in the return types of the search functions and related structures. The changes aim to enhance the output of these functions, allowing for more detailed information to be conveyed regarding search operations.

Changes

Files Change Summary
src/service/search/datafusion/exec.rs Modified the sql function to use session.target_partitions instead of cfg.limit.cpu_num for partition management in the with_partitions method of NewEmptyTable.
src/service/search/grpc/mod.rs Updated SearchTable type to include a usize for target partitions. Adjusted the search function to unpack and utilize this new value, ensuring target_partitions reflects the highest number encountered during searches.
src/service/search/grpc/storage.rs Altered the search function's return type to include an integer for target partitions. Updated return statements to reflect this change, enhancing the output information given to callers.
src/service/search/grpc/wal.rs Changed the return types of search_parquet and search_memtable functions to include an integer value. Updated return statements across multiple branches to ensure consistency with the new return structure.

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.

Line range hint 122-161: Approved: Updated logic in search function.

The updates to handle the new target_partitions logic are correctly implemented. Consider adding tests to verify that target_partitions is correctly updated based on the search results.

Would you like me to help in writing these tests?

47-47: Approved: Updated SearchTable type definition.

The addition of usize to the SearchTable type is consistent with the PR objectives. Ensure that this new type is used consistently throughout the file.

Verification successful

Verified: Consistent usage of updated SearchTable type.

The SearchTable type, updated to include usize, is used consistently across the relevant files. No issues found with its implementation or usage.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the usage of the new `SearchTable` type throughout the file.

# Test: Search for the usage of `SearchTable`. Expect: Only occurrences of the new type.
rg --type rust -A 5 $'SearchTable'

Line range hint 58-280: Approved changes with a suggestion to verify integration.

The function search_parquet now returns a super::SearchTable instead of a tuple, aligning with the new requirements to provide additional context through an integer value. The changes are consistent and correctly implemented across different return points.

Please ensure that the integration of the new return type super::SearchTable is compatible with the rest of the system, particularly where this function is called.


Line range hint 280-376: Approved changes with a suggestion to verify integration.

The function search_memtable now returns a super::SearchTable instead of a tuple, aligning with the new requirements to provide additional context through an integer value. The changes are consistent and correctly implemented across different return points.

Please ensure that the integration of the new return type super::SearchTable is compatible with the rest of the system, particularly where this function is called.

Adjustment to partition management in sql function.

The change from using cfg.limit.cpu_num to session.target_partitions for the with_partitions method in the NewEmptyTable instance is a significant shift. This adjustment allows for dynamic partitioning based on session-specific settings rather than a static configuration tied to CPU limits. This should provide more flexibility in handling different workloads and session requirements.

Ensure that the session.target_partitions is properly validated and falls within acceptable limits to prevent potential runtime issues due to misconfiguration.

Consider adding validation for session.target_partitions to ensure it's within a reasonable range before applying it as a partition parameter.
