PR: #18258. Related, from the same profile: the next-largest cost in that MERGE's target scan was building the position-delete indexes. `Deletes.toPositionIndexes` hashed and looked up the data-file path for every row, 20.5 % of the stage in JFR. That is already fixed on `main` by #17864 (not in a release yet). The two changes are independent: this one covers equality deletes, #17864 covers v2 position delete files. -- This is an automated message from the Apache Git Service.
