Description

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).
