Datadog has a similar use case for Partitioned Hash Join. Its files are well-partitioned and aligned, so P1, P2, and P3 share matching data ranges. Pushing down hash tables (HT1, HT2, HT3) to the corresponding probe-side partitions enables a significant performance boost. cc: @adriangb @LiaCastaneda <img width="568" height="397" alt="Image" src="https://github.com/user-attachments/assets/8f00ba7b-fb8b-46ec-8dfe-3aab4a44bec6"; /> -- This is an automated message from the Apache Git Service.
