Mikhail Stepura commented on CASSANDRA-7222:
--------------------------------------------
We can't fully rely on {{duration}}, see CASSANDRA-6317, but I'll take a look
what can be improved.
> cqlsh does not wait for tracing to complete before printing

> Key: CASSANDRA-7222
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7222
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Reporter: Tyler Hobbs
> Assignee: Mikhail Stepura
> Fix For: 2.0.9
>
>
> cqlsh currently sleeps 0.5 seconds before fetching trace info. Instead, it
> should fetch the {{system_traces.sessions}} row in a loop until the
> {{duration}} column is set (maybe with a total timeout of 30s). After the
> {{duration}} column is set, it's safe to fetch the rows from
> {{system_traces.events}}.
> This is already fixed in 2.1 by the switch to the python driver, we just need
> to fix 2.0.
