141-145: LGTM! Well-structured helper function
The build_key function is well-implemented with appropriate attributes and clear functionality.
96-127: Verify thread safety of OrderInfo updates
The code holds the lock while updating offset_next_visible_time, but we should verify there are no potential race conditions with other methods accessing the same data.
✅ Verification successful
Based on the gathered information, I can now provide the final response:
Thread safety implementation is correct and sufficient
The implementation uses parking_lot::Mutex to protect the shared state (ConsumerOrderInfoWrapper), and the lock is properly acquired for the entire duration of the update operation. The wrapper's internal state (HashMap) is only accessed while holding the mutex lock. Additionally:
- The
ConsumerOrderInfoWrappertype is marked aspub(crate), limiting access scope - The mutex is properly released after the operation as it uses RAII lock guard
- The update operation is atomic as all modifications happen while holding the lock

Critical: Implement update_lock_free_timestamp method
The method is currently unimplemented but is called by update_next_visible_time. This will cause a runtime panic when called.
Would you like me to help implement this method? Based on the method signature and usage context, it should update the lock-free timestamp in the OrderInfo structure.

🛠️ Refactor suggestion
Add documentation and improve error handling
The method lacks documentation explaining its purpose, parameters, and return value. Additionally, the error handling can be improved.
Consider these improvements:
+ /// Updates the next visible time for a specific queue offset in the order information.
+ ///
+ /// # Parameters
+ /// * `topic` - The topic name
+ /// * `group` - The consumer group name
+ /// * `queue_id` - The queue identifier
+ /// * `queue_offset` - The offset in the queue
+ /// * `pop_time` - The pop time to verify
+ /// * `next_visible_time` - The new next visible time to set

) {
let key = build_key(topic, group);
let mut table = self.consumer_order_info_wrapper.lock();
- let qs = table.table.get_mut(&key);
- if qs.is_none() {
+ let Some(qs) = table.table.get_mut(&key) else {
warn!(
"orderInfo of queueId is null. key: {}, queueOffset: {}, queueId: {}",
key, queue_offset, queue_id
);
return;
- }
- let qs = qs.unwrap();

warn!(
"orderInfo of queueId is null. key: {}, queueOffset: {}, queueId: {}",

💡 Codebase verification
Based on the verification results, I can now provide the final response:
Remove unused constant CLEAN_SPAN_FROM_LAST
The CLEAN_SPAN_FROM_LAST constant (24 hours in milliseconds) is defined but not used anywhere in the codebase. It should be removed to avoid confusion and maintain clean code.
🔗 Analysis chain
Verify usage of CLEAN_SPAN_FROM_LAST constant
The CLEAN_SPAN_FROM_LAST constant (24 hours in milliseconds) is defined but not used in the current implementation.
Let me search for potential usages in method implementations that might reference this constant.
Let me check if there are any other files in the codebase that might be using this constant through imports.
Let me check the content of these files to see if they might be using this constant.
