67-67: Added dependency: criterionThe addition of
criterionwithhtml_reportsfeature is appropriate for benchmarking purposes, especially since a new benchmark test is also introduced in this PR.
69-71: New benchmark configuration: "delivery"The configuration for the new benchmark "delivery" with
harnessset to false is correctly set up. This setting allows for custom benchmark harnesses, which is useful for specific benchmarking scenarios.rocketmq-store/benches/delivery.rs (1)
18-44: Benchmark Setup ReviewThe benchmark setup using
criterionis correctly implemented. The use oflazy_staticfor initializing data and the functionsdelivery1anddelivery2being benchmarked are appropriate. The benchmarks are well-structured, and the use of bitwise operations for indexing indelivery2is a good optimization.rocketmq-store/src/base/topic_queue_lock.rs (3)
48-52: Lock Function ImplementationThe lock function correctly calculates a hash and uses it to index into the vector of mutexes. This is an efficient way to distribute locks across different topics. The inline annotation is also appropriate here for performance.
55-76: Utility Functions: Hash Calculation and Table Size AdjustmentThe utility functions for hash calculation and adjusting the table size are correctly implemented and well-documented. The approach taken from Java's HashMap is a good choice for ensuring efficient hash table behavior.
78-116: Unit Tests forTopicQueueLockThe unit tests are comprehensive and cover various scenarios, including edge cases for the table size calculation. This ensures the reliability of the
TopicQueueLockimplementation.

TopicQueueLock Struct Implementation
The implementation of the TopicQueueLock struct is well-done. The use of Mutex for thread safety is appropriate. However, the presence of two size fields (size and size_) might be confusing. Consider renaming size_ to something more descriptive, like mask_size, to clarify its purpose.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
