Sylvain Lebresne commented on CASSANDRA-3688:
---------------------------------------------
I have nothing against that per se, but it's really in non-performance
sensitive code and so doesn't matter at all. And the replacement is slightly
more verbose. Overall I don't really care one way or the other but it does look
like change for the sake of change, which we probably should avoid.
> [patch] avoid map lookups in loops by using entrysets
