I was asked this question in one of my demos, and it was interesting one.
we update xmin for new inserts with the current txid.
now in a very high concurrent scenario where there are more than 2000
concurrent users trying to insert new data,
will updating xmin value be a bottleneck?
i know we should use pooling solutions to reduce concurrent
connections but given we have enough resources to take care of
spawning a new process for a new connection,
