[jira] [Created] (METRON-576) Stellar function resolution takes too long on running cluster

Nick Allen created METRON-576:
---------------------------------

             Summary: Stellar function resolution takes too long on running cluster
                 Key: METRON-576
                 URL: https://issues.apache.org/jira/browse/METRON-576
             Project: Metron
          Issue Type: Improvement
            Reporter: Nick Allen
            Assignee: Nick Allen


When running the Stellar REPL in a cluster on AWS, function resolution takes 50-60 seconds.  The user is not able to execute any functions in the REPL until this process completes.

The default function resolver searches the classpath for Stellar functions.  The delay may be because there are just too many classes in the classpath to search on a running cluster.  As more libraries are added as dependencies under /usr/metron/<version>/lib this problem just gets worse.
