Robert Stupp commented on CASSANDRA-10395:
------------------------------------------
Started working on this.
The benefit of this change is that we save UDF call latency caused by
scheduling the UDF call.
The downside is that an endless-loop-UDF will really never return and thus not
emit a warning to the client. CASSANDRA-9954 would bring back the warning for
Java-UDFs.

> Actually each UDF execution is handed over to a separate thread pool to be
> able to detect UDF timeouts. We could actually leave UDF execution in the
> "original" thread but have another thread/scheduled job regularly looking for
> UDF timeouts, which would save some time executing the UDF.
