XiaoHongbo-Hope opened a new pull request, #9360: URL: https://github.com/apache/paimon/pull/9360
## What changed - Materialize narrow matched update/delete rows before the file-routing shuffle in generic Ray MERGE. - Keep self-merge streaming and leave other row-id writers unchanged. ## Why When a lazy source already contains a join or shuffle, Ray can schedule the source join, MERGE target join, and file-routing shuffle in one streaming plan. On a 2-CPU cluster, shuffle aggregators can reserve the available resources and indefinitely starve the final routing stage. The new boundary separates the matched join from file routing without materializing the full source. ## Tests - Joined BLOB transform and matched update on 2 CPUs - Joined source and matched delete on 2 CPUs - Self-merge no-materialization regression - 127 Ray MERGE tests - 52 update/conflict/core commit tests - 24 table MERGE API tests - flake8, py_compile, and git diff check -- This is an automated message from the Apache Git Service.
