[jira] [Created] (METRON-1467) Replace guava caches in places where the keyspace might exceed 10k

Casey Stella created METRON-1467:
------------------------------------

             Summary: Replace guava caches in places where the keyspace might exceed 10k
                 Key: METRON-1467
                 URL: https://issues.apache.org/jira/browse/METRON-1467
             Project: Metron
          Issue Type: Improvement
            Reporter: Casey Stella


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
