[GitHub] [iceberg] akghbti commented on issue #4093: Merge (CopyOnWrite) Not Efficient as compared to equivalent Delete/Update Operation

@RussellSpitzer My point is why the Merge command (as shown in the case in this Issue) is overwriting 3 input part files when the search clause " t._c1='13' " (part of the merge clause) only satisfies 1 input part file. The search clause (on the input table) is not being pushed.
