Worked on the apache/rocketmq repository to enhance reliability and data integrity in distributed systems using Java. Focused on backend development and error handling, first by addressing client termination robustness through null safety checks that prevent crashes when client settings are missing. Improved cluster-wide correctness by ensuring system topics are consistently created across all brokers, simplifying operational management. Later, implemented a validation rule limiting group name length to 120 characters, applying this constraint across broker processors, subscription group management, and client-side validators. Added comprehensive unit tests to enforce the rule and prevent regressions, promoting consistency and maintainability throughout the codebase.
