Last small question: As of now parallelism in merge append is not supported, but it could be something we can consider implementing in the future. That said, I’m wondering if this might not be necessary, given that Gather Merge already accomplishes similar functionality. Would love to hear your thoughts on whether there’s a distinct advantage to adding parallelism to Merge Append or if Gather Merge sufficiently covers all the use cases. ----------------- Thanks, Ayush Vatsa SDE AWS
