Edward Ribeiro commented on CASSANDRA-275:
------------------------------------------

As far as I remember, this issue should be closed for now and future improvements on Map looping should be done on a case by case basis.

> When you iterates over all key-values of a Map is better to use entrySet() instead of a call to entryKey() and a call to get() inside the loop. It's more efficient. 
> I've seen a patch like this before, but I don't think it was applied at all.
