Sep 1, 2025

September 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.

December 2024: Delivered a configurable Hive Metastore Regression Test Setup in the Apache Doris project by refactoring regression test data handling to parameterize S3 bucket and endpoint. This enables dynamic construction of download URLs for diverse S3 configurations, increasing testing flexibility, reliability, and maintainability. The change reduces CI fragility and accelerates validation of Hive Metastore integration across providers.
