>                 Key: METRON-1467
>                 URL: https://issues.apache.org/jira/browse/METRON-1467
>             Project: Metron
>          Issue Type: Improvement
>            Reporter: Casey Stella
>            Priority: Major
>
> Based on the performance tuning exercise as part of METRON-1460, guava has difficulties with cache sizes over 10k.  We, unfortunately, are quite demanding of guava in this regard so we should transition a few uses of guava to Caffeine:
>  * Stellar processor cache
>  * The JoinBolt cache
>  * The Enrichment Bolt Cache
