> Key: METRON-1880
> URL: https://issues.apache.org/jira/browse/METRON-1880
> Project: Metron
> Issue Type: Improvement
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Major
>
> Caffeine is a more performant cache when cache sizes are larger. We've
> already seen a significant improvement elsewhere in Metron based on the work
> done in METRON-1467.
> The Profiler should use Caffeine for caching to ensure that the caches are
> not a performance bottleneck.
