July 2026 (2026-07) — Security and reliability enhancements were delivered for the mariadb-columnstore-engine, focusing on sustainable build stability and environment reliability improvements that support faster and safer releases. The team addressed security findings and reduced build fragility, ensuring smoother deployments on RockyLinux-based systems.

June 2026 performance and delivery summary for mariaDB ColumnStore components (mariadb-columnstore-engine and mariadb-docs). Focused on delivering robust time handling, stability, memory safety, and admin-facing documentation. Achievements span feature delivery, critical bug fixes, CI/QA hardening, and practical documentation improvements that translate to tangible business value including correct time arithmetic, improved query planning reliability, reduced memory-related issues, and clearer system administration guidance.

May 2026 focused on delivering robust DECIMAL arithmetic for MariaDB ColumnStore, consolidating and implementing DIV/MOD operations with strong overflow handling, NULL semantics, mixed-type paths, and precision improvements for AVG/SUM on narrow decimals. The work includes extensive tests and performance optimizations to ensure correctness, stability, and better analytics throughput, reducing the risk of truncation and incorrect results in high-precision workloads. Also adjusted math paths to utilize the decimal path (wide) for AVG/SUM on narrow decimals where beneficial, and strengthened edge-case handling to avoid undefined behavior.
