Geoffrey Yu commented on CASSANDRA-12367:
-----------------------------------------
Thanks for the first pass [~slebresne]! I added another commit to address your
comments
[here|https://github.com/geoffxy/cassandra/commit/a71968ebba8b67591b88cafd2daf3b37e17fec52].
I added {{rowCount()}} to the {{Partition}} interface to be able to pass in a
{{rowEstimate}} to {{UnfilteredRowIteratorSerializer.serializedSize()}} since
all the implementing classes already had that method available. Please let me
know how it looks now!

Wonders if it wouldn't be more user friendly to return 0 if the key is not
hosted on that replica (which will simply happen if we don't check anything).
Genuine question though, I could see both options having advantages, so
mentioning it for the sake of discussion.

I don't feel strongly either way since I also agree that both options have
merit. I've left the check in for now but I have no objection to removing it if
others feel strongly.
