Subject [jira] Commented: (CASSANDRA-275) Replace Map.keySet by more efficient Map.entrySet
Date Tue, 07 Jul 2009 23:07:14 GMT


Edward Ribeiro commented on CASSANDRA-275:

Really. Well, I propose to get rid of this patch altogether, but my previous comment is still

Some places of the code base look pretty bad. Anyone could get in charge of fixing these in
the future?

> 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.
