705-719: LGTM! Consider adding documentation.The implementation is clean and thread-safe with proper atomic operations. However, it would benefit from documentation explaining the relationship with
select_mapped_buffer.Add documentation explaining:
- When to use this vs
select_mapped_buffer- The meaning of the return value's fields
- Thread safety guarantees

497-515: Verify the impact of removing mapped_file reference.The implementation sets
mapped_file: Nonein the result, which might affect callers expecting a valid reference. Additionally, the change fromArc<Self>to&selfcould impact thread safety.Run this script to find potential unsafe usages:
rocketmq-store/src/log_file/mapped_file.rs (1)
178-205: LGTM! Well-documented trait methods.The new trait methods are clearly documented with their purpose, parameters, and return values. The documentation helps users understand when to use each method.
rocketmq-store/src/log_file/commit_log.rs (2)
283-287: LGTM! Proper mapped file tracking.The changes correctly update the mapped file reference in the result, maintaining the connection between the buffer and its source file.
1135-1139: LGTM! Consistent mapped file handling.The changes maintain consistency with the get_message method in how mapped files are tracked in the result.
rocketmq-store/src/queue/single_consume_queue.rs (2)
340-345: LGTM! Proper buffer selection with position.The implementation correctly uses the new position-based buffer selection and maintains the mapped file reference.
639-645: LGTM! Consistent buffer selection.The implementation maintains consistency with other changes in how mapped buffers are selected and tracked.

Critical: Implement commit functionality before deployment.
The commit function is marked as unimplemented, which will cause runtime panics. This is a breaking change from the previous implementation that returned 0.
This functionality needs to be implemented before the code can be deployed to production. Consider either:
- Implementing the commit functionality, or
- Maintaining the previous behavior of returning 0 until the new implementation is ready
