Over a two-month period, contributed to the apache/doris repository by developing three core features focused on database command enhancements and administrative tooling. Built and integrated the Refresh Table Command in Nereids, allowing users to refresh specific tables and improve metadata consistency without manual intervention. Extended DorisParser and implemented command pattern techniques in Java and ANTLR to support new SQL syntax and execution paths. Further work included adding ALTER DATABASE RENAME and SHOW CONVERT_LSC commands, enhancing database renaming workflows and schema change observability. All changes were validated against Doris master, emphasizing parser development, SQL parsing, and maintainable code generation practices.
