Reid Chan contributed to backend and distributed systems engineering across the milvus-io/milvus and Apache HBase repositories, focusing on performance, observability, and data management. In Milvus, Reid enhanced proxy metrics by adding collection-level granularity to vector deletion tracking and corrected metric labeling to improve monitoring accuracy, using Go for backend development. For Apache HBase and the HubSpot fork, Reid implemented per-column-family storage policy customization in ExportSnapshot, enabling fine-grained data placement and policy enforcement during snapshot exports. These changes, developed in Java, addressed cross-repository consistency and provided more flexible, cost-efficient storage management for large-scale data workflows.

April 2025 monthly summary focusing on key accomplishments: Delivered storage policy customization for ExportSnapshot across Apache HBase and HubSpot's fork, enabling per-column-family storage policy specification during snapshot export. Implementations address HBASE-29238 with commits associated to the policy feature. HubSpot HBase fork extends this with CLI options and updated export logic to enforce policies, achieving cross-repo parity and consistent behavior across environments. The change enables finer-grained data placement decisions, potential storage cost optimization, and improved performance for snapshot workflows.
