Joshua McKenzie updated CASSANDRA-12062:
----------------------------------------
Reviewer: Joshua McKenzie
> Prevent key invalidation if there's no key to invalidate
> --------------------------------------------------------
>
> Key: CASSANDRA-12062
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12062
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Robert Stupp
> Assignee: Robert Stupp
> Priority: Minor
> Fix For: 3.x
>
>
> In {{SSTableRewriter}} we currently assume that there are keys to be
> invalidated in the key cache. That's not always true - especially if a bunch
> of tiny sstables have been generated.
> Patch saves one {{synchronized}} and a few objects if that's the case.
> Just a small optimisation, but maybe worth to include.
