Over two months, contributed to the apache/doris repository by enhancing SQL parsing and improving backend reliability. Developed support for loading data into temporary partitions by extending the DorisParser.g4 grammar using ANTLR and Java, and integrated comprehensive regression tests to ensure correctness. Addressed critical memory safety issues in C++ by fixing buffer access and string reserve size calculations, reducing the risk of core dumps during data ingestion. Corrected a schema typo in TPCDS test configurations to maintain data integrity. Focused on backend development, bug fixing, and database schema management, these efforts strengthened production stability and improved data loading workflows.
