>
> 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
