How did you ensure that this is sufficient? For parallel-insert's
patch we have enabled parallel-mode for Inserts and ran the tests with
force_parallel_mode to see if we are not missing anything. Also, it
seems there are many common things here w.r.t parallel-insert patch,
is it possible to prepare this atop that patch or do you have any
reason to keep this separate?
