Over a two-month period, contributed to the apache/fluss repository by implementing JBOD Phase 1 Local Multi-Directory Storage for the TabletServer, enabling the use of multiple data directories and updating both TabletManager and LogManager to coordinate data across these directories. This work improved storage scalability and data isolation, laying groundwork for future enhancements. In addition, stabilized the test suite by fixing the Disk Usage Collector test to accurately compare results across directories, reducing flaky outcomes and improving CI reliability. Demonstrated skills in Java, backend development, data storage management, assertions, and unit testing, with a focus on maintainability and collaborative development.
