Odyssey 1.5.1, the multi-threaded connection pooler for PostgreSQL and Apache Cloudberry, has been released. New features include simple shared pools, pool_pin_on_listen for transaction pooling, cpu_affinity support, AWS-LC build support, SSLKEYLOGFILE support, queue time metrics (avg_wait_time/total_wait_time), improved Prometheus metrics exporter, and more. Bug fixes address pool size rechecking, cancel support race conditions, auth_query issues, and extended protocol handling for Close, DEALLOCATE ALL, and COPY. Extended protocol support was also refactored with pipelining performance improvements. Version 1.5.2 is already in preparation.
