43-54: Add documentation for newly introduced fields.
Thebroker_config,topic_config_manager,consumer_offset_manager, andescape_bridgefields significantly impact how thePopReviveServiceinteracts with broker-level configurations and offset management. Consider adding doc comments to clarify their purpose.
83-145: Avoid overwriting or duplicating tags/properties.
Insiderevive_retry, lines 107–110 set the tags from the original message if present; otherwise, they set an empty property map. Then line 118 callsMessageAccessor::set_propertiesagain, cloning the entire property set from the originalmessage_ext.

147-164: Ensure new topics are consistently visible across the system.
When callingadd_retry_topic_if_not_exist, a new topic configuration is inserted. Please verify that other broker components (e.g., routing and metadata) pick up newly added topics so messages aren't dropped.✅ Verification successful
Let me gather more information about how topic configurations are handled in the broker runtime.
Topic registration is properly handled through the broker runtime system
The verification shows that topic configurations are properly propagated across the system:
- When a new topic is created via
update_topic_config, theTopicConfigManagerautomatically callsregister_broker_datafor new topics- The registration process:
- Spawns an async task to handle the registration
- Uses
register_single_topic_allto propagate the topic to all name servers whenenable_single_topic_registeris enabled- Updates permissions and broker metadata as needed
The code follows a robust pattern for topic registration and visibility across the broker system, ensuring new topics are properly tracked and accessible.

The following scripts were executed for the analysis:

22-42: Consider grouping and re-checking imports for potential duplication or unnecessary modules.
While the introduced imports (for exampleBrokerConfig,TopicConfig, and more) seem necessary for the new functionality, please verify that every imported item is used to avoid cluttering the namespace.✅ Verification successful
Let me verify the usage of these imports in the actual code.
All imports are actively used in the code
Based on the search results, every imported module and type is being used within the file:

Line range hint
57-81: Initialization logic is consistent, but consider verifying concurrency assumptions.
The constructor properly initializes the new fields, but if multiple threads instantiate or mutatePopReviveService, ensure concurrency assumptions hold. In particular, confirm that theTopicConfigManagerandConsumerOffsetManagerusage remains thread-safe or is only used within a single-thread context.✅ Verification successful
Thread-safety is properly implemented through synchronized data structures
The code inspection reveals that
PopReviveServiceis designed with thread-safety in mind:
- The
inflight_revive_request_mapis wrapped in bothArcandparking_lot::Mutex, providing thread-safe access to the shared state- Thread-safe components are used for shared resources:
Arc<ConsumerOffsetManager>for consumer offset managementArc<BrokerConfig>for broker configurationArcMut<EscapeBridge>for escape bridge accessThe concurrency concerns in the review comment are already addressed through proper use of synchronization primitives. The implementation correctly handles concurrent access through atomic reference counting and mutex protection where needed.

🛠️ Refactor suggestion
Initialization with offset 0 might need a more detailed rationale.
If the offset is missing (“< 0”), you commit offset = 0. Consider whether resuming at offset 0 for existing topics might accidentally reprocess older messages or skip messages. A comment or doc note explaining this initialization decision would help maintainers.
