- Move FLUSHED_POSITION_UPDATER.set() inside try block
- Prevent false positive flush success when actual flush operation fails
- Ensure data consistency and prevent potential data loss on system crash
Previously, flushed position was updated even when flush operation failed,
which could lead to data loss as the system would incorrectly assume
data was persisted to disk when it was still in memory.

* Cherry-pick partial changes from 67db1757df - BrokerMetricsManager refactoring
- Excluded DefaultMappedFile, METRICS_REFACTORING_GUIDE.md, TimerMetrics, and RocksDB files per requirements
- Successfully applied changes to most broker and store modules
- Compilation errors in TimerMessageStore.java will be fixed in next commit
* fix: Resolve metrics static variable conflicts in BrokerContainer mode
Convert static metrics variables to instance-level to fix resource leaks and
data conflicts in BrokerContainer scenarios with multiple broker instances.
## Problem Statement
In BrokerContainer mode, multiple broker instances share static metrics variables
from BrokerMetricsManager and DefaultStoreMetricsManager, causing:
- Metrics data conflicts between different broker instances
- Resource leaks during frequent addBroker/removeBroker operations
- Incorrect metrics aggregation across multiple brokers
## Solution
- Convert static metrics variables to instance-level variables
- Add proper getter methods for external access
- Ensure each broker instance maintains isolated metrics
- Apply instanceof checks for type safety in TimerMessageStore
## Files Modified
- broker/src/main/java/org/apache/rocketmq/broker/metrics/BrokerMetricsManager.java
- store/src/main/java/org/apache/rocketmq/store/timer/TimerMessageStore.java
- METRICS_REFACTORING_GUIDE.md (documentation)
## Key Benefits
✅ Eliminates metrics conflicts between broker instances
✅ Prevents resource leaks in dynamic broker scenarios
✅ Maintains proper metrics isolation per broker
✅ Supports BrokerContainer mode with multiple brokers
✅ Backward compatible with existing functionality
Resolves metrics static variable issues in multi-broker container environments.
* Delete useless file
* Fix test can not pass
* Fix test can not pass
* Initially optimize the broker container structure
* refactor: Improve BrokerContainer extensibility and logging
This commit enhances the BrokerContainer module to improve code structure
and logging capabilities:
Key improvements:
- Polish the code structure to make BrokerContainer more extensible
- Improve container logging configuration and management
- Enhance BrokerBootHook for better hook management
- Update BrokerContainer and BrokerContainerProcessor for improved functionality
- Remove unused BrokerLogbackConfigurator to reduce complexity
- Update BrokerStartup and BrokerController for better container integration
Modified files:
- broker/src/main/java/org/apache/rocketmq/broker/BrokerController.java
- broker/src/main/java/org/apache/rocketmq/broker/BrokerStartup.java
- container/src/main/java/org/apache/rocketmq/container/BrokerBootHook.java
- container/src/main/java/org/apache/rocketmq/container/BrokerContainer.java
- container/src/main/java/org/apache/rocketmq/container/BrokerContainerProcessor.java
- container/src/main/java/org/apache/rocketmq/container/BrokerContainerStartup.java
- container/src/main/java/org/apache/rocketmq/container/logback/BrokerLogbackConfigurator.java (removed)
This refactoring improves the overall maintainability and extensibility
of the container module while maintaining backward compatibility.
* test: Add unit tests for BrokerContainer extensibility improvements
This commit adds comprehensive unit tests for the BrokerContainer
extensibility improvements introduced in this branch:
Key test coverage:
- BrokerBootHook system extensibility and proper hook execution
- Container configuration accessibility and management
- Container initialization and lifecycle management
- BrokerContainerProcessor integration
- Startup and shutdown sequence robustness
- Extension points and customization capabilities
These tests ensure that the improved BrokerContainer architecture
maintains backward compatibility while providing enhanced extensibility
for future development and customization.
* Fix testBrokerGracefulShutdown can not pass
* Fix BrokerContainerExtensibilityTest can not pass
* fix(container): add missing auth module dependency
- Add //auth dependency to container target in BUILD.bazel
- Add //auth dependency to tests target in BUILD.bazel
- Fixes compilation errors for AuthConfig class usage
- Resolves Bazel build failures in container module
Fixes: symbol not found org.apache.rocketmq.auth.config.AuthConfig
* feat: Add accelerated startup recovery feature
Add accelerated startup recovery functionality when using RocksDB store with SYNC_FLUSH configuration:
- Add enableAcceleratedRecovery configuration option in MessageStoreConfig
- Implement accelerated recovery logic in CommitLog for both normal and abnormal recovery
- Add protective fallback mechanism to handle edge cases
- Improve isMappedFileMatchedRecover method for better robustness
- Add comprehensive unit tests for the accelerated recovery feature
This feature significantly reduces startup time when recovering from RocksDB-based storage
with synchronous flushing enabled, while maintaining data consistency and safety.
* Fix the issue of accelerated startup failure
* refactor: Remove problematic unit test
Remove AcceleratedRecoveryTest.java as the test implementation was not appropriate for the accelerated startup recovery feature.
* Delete useless code
* limit group length to 120 for max length for pop retry topic is 255.
* Add unit test for validating group.
* Fix unit test for validating gRPC group, limit length to 120
