[jira] Commented: (CASSANDRA-275) Replace Map.keySet by more efficient Map.entrySet

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12728136#action_12728136 ] 

Jonathan Ellis commented on CASSANDRA-275:
------------------------------------------

Minor problem: this patch does not follow Cassandra code conventions

Bigger problem: using entrySet is uglier than iterating keys and calling get in many situations.  I'm -1 on doing a blanket replace in the name of efficiency.

> 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.
