Sylvain Lebresne commented on CASSANDRA-11521:
----------------------------------------------
bq. WRT CL, with this approach, I don't quite see why you would have to stick
to CL_ONE here
It's more a matter of CL.ONE being the case where we know we can get great
benefits. Because in that case we'll "keep the query open", which save tons of
work that is done for every page otherwise. For other CLs, because we asks
other nodes, we'd kind of have to add some intra-node streaming of results to
get substantial gains. And that's a lot more involved, hence the "that's an
optimization for another day".
