Walkthrough

The pull request introduces modifications to the ConsumeMessageServiceTrait across multiple consumer implementation files in the RocketMQ client. The primary changes involve removing unused core pool size management methods and adding default implementations for these methods in the trait. The modifications simplify the trait's interface by providing empty implementations for methods like update_core_pool_size, inc_core_pool_size, and dec_core_pool_size. Additionally, get_core_pool_size now returns the number of available CPUs by default.

Changes

File Change Summary
rocketmq-client/src/consumer/consumer_impl/consume_message_*.rs Removed unused core pool size management methods:
- update_core_pool_size
- inc_core_pool_size
- dec_core_pool_size
- get_core_pool_size
consume_message_service.rs Added default implementations for removed methods:
- Empty implementations for most methods
- get_core_pool_size now returns num_cpus::get()

Poem

🐰 Hop, hop, through the code we go,
Trimming methods that were just for show
Default implementations, clean and bright
Making our trait interface light and tight!
RocketMQ's rabbit says, "Simplify with might!" 🚀

283-285: Enhance default implementation of get_core_pool_size

While using num_cpus::get() is a reasonable default, consider:

  1. Adding documentation explaining why CPU count is the default
  2. Allowing configuration through environment variables or builder pattern
  3. Providing guidance for implementors with different requirements (e.g., I/O-bound workloads)

Consider this enhanced implementation:

fn get_core_pool_size(&self) -> usize {
    // First check for environment variable
    if let Ok(size) = std::env::var("ROCKETMQ_CORE_POOL_SIZE") {
        if let Ok(size) = size.parse::<usize>() {
            return size;
        }
    }
    // Fall back to CPU count as a reasonable default
    num_cpus::get()
}

Let's verify if any implementors override this method:

Line range hint 1-285: Address incomplete refactoring of pool size management

The trait now provides default implementations for pool size management, but both ConsumeMessageServiceGeneral and ConsumeMessagePopServiceGeneral still have todo!() implementations. This suggests incomplete refactoring.

Consider:

  1. Removing the todo!() implementations to use the trait's defaults
  2. Or document why these services need custom implementations

Let's verify the state of other consumer implementations:

270-276: Document the rationale for empty default implementations

The empty default implementations for pool size management methods suggest these methods are optional or being deprecated. Please add documentation explaining:

  • Why these methods can have empty implementations
  • Whether these methods are deprecated or optional
  • Impact on existing implementations that may rely on these methods

Let's verify the usage of these methods across the codebase:

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.
