[jira] [Created] (CASSANDRA-8467) Tracing for UDFs

Robert Stupp created CASSANDRA-8467:
---------------------------------------

             Summary: Tracing for UDFs
                 Key: CASSANDRA-8467
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8467
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Robert Stupp
            Priority: Minor


This thicket's about to add UDF executions to session-tracing.

Tracing these parameters for UDF invocations could become very interesting.
* name of UDF
* # of invocations
* # of rejected executions
* min/max/avg execution times

"Rejected executions" would count UDFs that are not executed because an input parameter is null/empty (CASSANDRA-8374).
