In February 2026, Chengchu developed a JDBC-backed storage backend for partition statistics in the apache/gravitino repository, enabling seamless integration with relational databases such as MySQL, PostgreSQL, and H2. Leveraging Java and SQL, Chengchu designed the solution to provide transactional guarantees for updates, enhancing data durability and supporting backup and recovery workflows. The backend was implemented as a pluggable configuration, ensuring compatibility with existing Lance storage without introducing breaking changes. This work demonstrated a strong grasp of database management and software development principles, delivering a robust, flexible storage option that aligns with enterprise infrastructure requirements and collaborative engineering standards.
