----------------------------------------
Assignee: Chris Goffinet
> Fix Findbugs: Replace keySet w entrySet
> ---------------------------------------
>
> Key: CASSANDRA-611
> URL: https://issues.apache.org/jira/browse/CASSANDRA-611
> Project: Cassandra
> Issue Type: Bug
> Reporter: Stu Hood
> Assignee: Chris Goffinet

>
> A lot of places in the codebase, we iterate over the keySet() of a Map, and
> call get() for each key. For a HashMap, this is still O(N), but when you are
> dealing with a SortedMap, this is O(NlogN). The list of occurences are
> attached.
> Fixing this issue should give us a general (minor?) performance boost.
> In order to find unused method parameters for CASSANDRA-608, I ran FindBugs
> against Cassandra, and found a few interesting issues we ought to explore
> (but not the unused method params, oi.)
