37-37: Visibility change fortopic_queue_lockmodule.Making the
topic_queue_lockmodule public increases its accessibility across the application. Ensure that this change aligns with the intended use cases and does not expose internal details unnecessarily.Verification successful
Visibility change for
topic_queue_lockmodule verified.The public visibility of the
topic_queue_lockmodule is justified as it is utilized inrocketmq-store/src/log_file/commit_log.rs. This change aligns with the PR's objectives to optimize theCommitLog#put_messagemethod and introduce aTopicQueueLock.

389-389: Change in default value fortopic_queue_lock_numfrom 0 to 32This change is consistent with the PR objectives to optimize locking by potentially reducing contention with multiple locks. However, ensure this new default does not adversely affect existing deployments, especially in environments where the default was sufficient or where resource constraints are tighter.

63-63: Import ofTopicQueueLockThe import statement for
TopicQueueLockis correctly placed and necessary for the changes in this file.
196-196: Addition oftopic_queue_locktoCommitLogstruct and its initializationThe addition of the
topic_queue_lockfield to theCommitLogstruct is aligned with the PR's objective to optimize message handling. The lock is properly initialized using thetopic_queue_lock_numfrom the configuration, which allows for configurable concurrency levels.Also applies to: 232-234

Usage of topic_queue_lock in message handling methods
The lock is used in put_messages and put_message methods to synchronize access to shared resources based on the topic and queue ID. This should help in reducing contention and improving throughput in high-load scenarios. However, consider adding error handling for lock acquisition failures and ensure that the lock is always released, even in case of exceptions, to prevent deadlocks.
+ try {
+ let topic_queue_lock = self.topic_queue_lock.lock(topic_queue_key.as_str()).lock().await;
+ } catch (error) {
+ // handle lock acquisition failure
+ return PutMessageResult::new_default(PutMessageStatus::LockAcquisitionFailed);
+ }
+ // ensure lock is released
+ drop(topic_queue_lock);Also applies to: 474-474, 545-549, 662-662
