Tian Bao

Contributed to the apache/gravitino repository by delivering features and fixes focused on backend stability, data engineering, and cross-platform compatibility. Developed partition management for the Spark Hive connector, enabling add, list, and drop operations across data types to improve Hive table handling. Addressed dependency conflicts in Spark Connector packaging and enhanced Java 8 compatibility through Gradle build configuration updates. Improved S3 catalog integration by resolving configuration mapping issues and test flakiness on macOS and Windows, leveraging Docker and Java for robust test automation. Work emphasized clear documentation, commit-driven delivery, and careful management of build systems, dependencies, and distributed system configurations.

June 2026 — Apache Gravitino: S3 catalog stability improvements and cross-platform test reliability. Key features delivered: corrected S3 path-style access mapping and S3 endpoint handling to support macOS LocalStack in FilesetS3CatalogIT. Major bugs fixed: FilesetS3CatalogIT no longer hangs on macOS due to missing mapping of GRAVITINO_S3_PATH_STYLE_ACCESS to PATH_STYLE_ACCESS and updated endpoint access usage; test endpoint connectivity fixed by using localhost:port. Overall impact: significantly improved cross-platform S3 integration stability, reduced test flakiness, enabling smoother development and CI on macOS/Windows. Technologies/skills demonstrated: Hadoop S3A, LocalStack, Docker, macOS/Windows compatibility, Java tests, test automation, and configuration propagation.

May 2025 monthly summary for apache/gravitino. Key features delivered include Partition management for Spark Hive connector, enabling add/list/drop partitions across data types and improving handling of partitioned Hive tables. Major bugs fixed include a packaging-level logging dependency conflict in the Spark Connector by removing slf4j from packaging, which reduces runtime issues and stabilizes backend performance without user-facing changes. Overall impact: enhanced data pipeline reliability and performance, smoother Spark-based deployments, and reduced maintenance overhead due to more robust packaging. Technologies demonstrated: Spark ecosystem (Spark Hive connector), partition management, dependency/packaging management, and commit-driven development.
