May 2026 focused on delivering the HBase Read Replica Cluster feature, enabling scalable management of read replicas with procedures to refresh HFiles and metadata. The work introduced new classes and methods to support read replica functionality, improving read performance and reliability in multi-cluster deployments. This feature rollout aligns with our objective to enhance data availability for read-heavy workloads and provides a solid foundation for further replication capabilities. No major bug fixes are documented for this month in the provided data.

February 2026 monthly summary for apache/hbase focusing on delivering a targeted feature to improve testing fidelity and data retrieval consistency.

May 2025 summary: TLS watcher reliability improvements across two major HBase forks (apache/hbase and HubSpot/hbase). By making the NettyTLSIPCFileWatcher polling interval configurable, the system can detect keystore/truststore changes faster, enabling reliable TLS reloads in tests and in production, reducing flakiness and operational risk. The changes provide a consistent, configurable TLS watcher approach across repositories and align with the HBASE-29181 effort.

Month: 2025-01. Focused on security enhancements and extensibility for HBase RPC by delivering a new certificate-based authorization pathway. Key features delivered: - RPC Authorization Coprocessor with certificate-based authentication. Introduced a coprocessor hook for RPC authorization, enabling interception and authorization of connections based on client SSL certificate chains. Implemented the necessary interfaces and observer classes and integrated the hooks into the RPC server's connection handling to enable granular, certificate-based access control. Commit: d477bf163bf51d38e6596131f6608da6f9597f95 (HBASE-28952: Add coprocessor hook to authorize user based on client SSL certificate chain (#6447)). Major bugs fixed: - None reported/major bugs fixed this period. Overall impact and accomplishments: - Strengthened security posture by enabling certificate-based RPC authorization across the cluster, reducing the risk of unauthorized access through RPC channels. - Created a scalable extension point for future authorization policies and audits, aligning with enterprise compliance requirements. - Delivered a concrete, testable path to enforce access at the connection layer, enabling more granular control per client certificate chain. Technologies/skills demonstrated: - Java-based coprocessor design and extension points in HBase. - Mutual TLS (mTLS) integration concepts and client certificate chain-based authorization. - API/interface design for coprocessors and observers, and integration into server lifecycle. - Collaboration and traceability through a documented commit linked to a tracked issue.
