1085-1086: Log topic deletion.The code logs the deletion of the topic, which is useful for debugging and auditing.
Consider adding more context to the log message, such as the number of queues deleted.
info!("DeleteTopic: Topic has been destroyed, topic={}, queues_deleted={}", topic, queue_table.len());

118-118: LGTM! But verify the method usage in the codebase.The changes to the method signature and return type are approved.
However, ensure that all calls to
delete_topicsmatch the new signature.rocketmq-common/src/common/broker/broker_config.rs (1)
165-165: Addition ofauto_delete_unused_statsfield approved.The new field enhances the configuration by allowing automatic deletion of unused statistics, with a default value of
false.rocketmq-common/src/utils/util_all.rs (1)
254-273: Addition ofdelete_empty_directoryfunction approved.The function is a useful utility for deleting empty directories with appropriate error logging.
rocketmq-store/src/queue.rs (1)
288-289: Addition ofget_consume_queue_tablemethod approved.The method enhances the trait by providing access to the consume queue table.

391-400:
LGTM! The mutable reference is appropriate.The change to accept a mutable reference to
selfin thedelete_topic_in_brokerfunction is appropriate as it allows the function to modify the state ofself.rocketmq-store/src/queue/local_file_consume_queue_store.rs (5)
61-61: LGTM! Improved thread safety.Changing the
consume_queue_tablefield to anArc<ConsumeQueueTable>improves thread safety and allows it to be shared across multiple threads.
88-88: LGTM! Consistent initialization.The
newmethod correctly initializes theconsume_queue_tableas anArc<parking_lot::Mutex<HashMap<String, TopicConfig>>>, consistent with the changes made to theInnerstruct.
154-156: LGTM! Correct usage ofget_life_cycle.The
destroy_consume_queuemethod correctly uses theget_life_cyclemethod to obtain afile_queue_life_cycleand calls itsdestroymethod.
287-287: LGTM! Correct usage ofqueue_offset_operator.The
remove_topic_queue_tablemethod correctly uses thequeue_offset_operatorto remove a topic queue table.
389-391: LGTM! Correct implementation.The
get_consume_queue_tablemethod correctly returns a clonedArc<ConsumeQueueTable>.rocketmq-store/src/stats/broker_stats_manager.rs (1)
489-489: LGTM! Correct implementation.The
on_topic_deletedmethod correctly handles topic deletion events.rocketmq-store/src/message_store/default_message_store.rs (8)
1046-1048: Check for empty topic list early.The early return for an empty topic list is appropriate.
1050-1052: Initialize delete count.The delete count is initialized correctly.
1052-1056: Handle missing consume queue map.The code correctly handles the case where the consume queue map for a topic is missing.
1057-1062: Destroy and remove consume queues.The code correctly destroys and removes consume queues for the topic.
1064-1065: Remove topic from consume queue table.The code correctly removes the topic from the consume queue table.
1067-1072: Auto-delete unused stats.The code correctly handles the auto-deletion of unused stats if the broker configuration allows it.
1074-1084: Delete associated directories.The code correctly deletes the associated directories for the topic.
1088-1089: Return delete count.The function correctly returns the count of deleted topics.
