Apr 1, 2025April 2025 performance summary for apache/cassandra: Focused on release engineering and streaming stability. Delivered 5.0.5 release readiness by updating release notes, CHANGES, Debian changelog, and version entries to reflect accurate release details. Fixed a bug to honor MAX_PARALLEL_TRANSFERS in Cassandra streaming, replacing default usage with the configured limit to improve throughput and stability. These efforts reduce release risk, speed up time-to-market for critical updates, and improve operational reliability across environments. Technologies demonstrated include release tooling, changelog management, Debian packaging conventions, and streaming configuration handling.
