Review Comment:
Seems that we retrieve esitmated size for all tables twice, once
withinlocalPartitionStateWithLogIndex() and one more time within newly
introduced estimatedSizeMap. Is that because of compatibility?

Review Comment:
What about compatibility? Let's say that new node retrieves
localPartitionStateMessage from the old node (I'm talking about rolling update
scenario) where there's no such field `partitionIdToEstimatedRowsMap`.
