January 2026 – Stability and reliability improvements for counting aggregates in pinterest/starrocks. Delivered a fix for a memory leak in the registration of count aggregate functions. The change, committed as f3848e9676f47eb8023b9c4e9c13703d0b413dcf, ensures stable memory usage during function calls and reduces risk of memory growth under concurrent workloads. This supports more predictable COUNT-based analytics and reduces support incidents related to memory pressure.
