Subject [jira] [Commented] (CASSANDRA-7645) cqlsh: show partial trace if incomplete after max_trace_wait
Date Wed, 04 Nov 2015 20:02:27 GMT


Carl Yeksigian commented on CASSANDRA-7645:

We should revert these changes from 2.1, as we didn't change to the new driver architecture
in the 2.1 update. Otherwise, I've updated to use the new API from PYTHON-438.

> If a trace hasn't completed within {{max_trace_wait}}, cqlsh will say the trace is unavailable
and not show anything.  It (and the underlying python driver) determines when the trace is
complete by checking if the {{duration}} column in {{system_traces.sessions}} is non-null.
 If {{duration}} is null but we still have some trace events when the timeout is hit, cqlsh
should print whatever trace events we have along with a warning about it being incomplete.
