------------------------------------
Status: Ready to Commit (was: Patch Available)
> RestrictionSet.hasIN() is slow
> ------------------------------
>
> Key: CASSANDRA-12153
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12153
> Project: Cassandra
> Issue Type: Improvement
> Components: Coordination
> Reporter: Tyler Hobbs
> Assignee: Tyler Hobbs
> Priority: Minor
> Fix For: 3.x
>
>
> While profiling local in-memory reads for CASSANDRA-10993, I noticed that
> {{RestrictionSet.hasIN()}} was responsible for about 1% of the time. It
> looks like it's mostly slow because it creates a new LinkedHashSet (which is
> expensive to init) and uses streams. This can be replaced with a simple for
> loop.
