Zheng Gaoxiong contributed to the apache/doris repository by engineering robust cloud storage and data integration solutions, focusing on Hive Metastore, Paimon, and Apache Ranger. He enhanced regression and integration testing by parameterizing S3 configurations, expanding test coverage for multi-cloud backends, and implementing Docker-based deployment improvements. Using Shell scripting, SQL, and Docker Compose, Zheng streamlined environment provisioning, automated policy enforcement validation, and improved CI reliability. His work addressed complex scenarios such as Kerberos authentication, resource-level access control, and parallel data preparation, resulting in more maintainable, flexible, and reliable data infrastructure for distributed systems and cloud-native data warehousing environments.

Sep 1, 2025September 2025 monthly summary focusing on cloud storage integration and deployment reliability for Apache Doris (apache/doris). Delivered Paimon cloud storage integration with cloud backends (GCS, HDFS with Kerberos, and GCS filesystem) including time travel, batch incremental reads, and system tables; expanded tests for multiple cloud storage backends and refined catalog properties to improve reliability. Strengthened Hive Docker deployments with larger heap, more task retries, improved JAR management, and a new parallel data preparation flag, plus refactored data preparation scripts to boost reliability and efficiency.

Aug 1, 2025In 2025-08, delivered expanded Hive Metastore (HMS) integration for Paimon across multiple cloud backends (S3, OSS, OBS, COS), enhanced test coverage for Paimon catalog properties, and aligned HMS test data with COS expectations. These efforts broaden storage compatibility, improve testing reliability, and reduce integration risk for cloud-storage scenarios affecting customers relying on Paimon HMS.

May 1, 2025May 2025 monthly work summary for apache/doris: Focused on streamlining Dockerized Hive environment provisioning by adding a NEED_LOAD_DATA environment flag to optionally skip loading test data, reducing setup time when only environment provisioning is required. This change improves developer onboarding, CI speed, and overall testing efficiency. Implemented via commit 3bca44ca09e55631cbd85cd3fe9c1c3a78be140e (#51065).
