PROFILE
Kkop
Jibing Li contributed backend features to the Jibing-Li/incubator-doris repository, focusing on storage optimization and data ingestion reliability. Over two months, he developed the ability to modify the storage_medium property for tables during ALTER operations, updating core components and adding regression tests to ensure robust behavior. He also enhanced the stream-load process by implementing automatic deletion of temporary files after successful imports and integrating disk space checks during directory allocation, validated by new test cases. His work demonstrated depth in backend development, database management, and system optimization, using Java and SQL to deliver maintainable, business-focused improvements without major bug fixes.
