This article dives deep into cxpacket and cxconsumer in sql server, explaining how to simulate each, when they appear, and why they matter. Using live execution plans, wait monitoring, and worker thread diagnostics, we uncover how uneven parallelism triggers thread sync waits—and how SQL Server sometimes hides real issues behind innocent-looking CXCONSUMER waits. Includes step-by-step queries, tuning tips, and a real-world scenario where repartition streams quietly ruined performance.

SQL Server 2025 improved PSPO to handle multiple predicates that might have parameter sensitivity, and that’s great! I love it when Microsoft ships a v1 feature, and then gradually iterates over to make it better. Adaptive Memory Grants were a similar investment that got improved over time, and today they’re fantastic.
