-------------------------------------------
[~snazy] was this part of what you did in 3.8?
> With tracing enabled, queries should still be recorded when using prepared
> and batch statements

> Key: CASSANDRA-7021
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7021
> Project: Cassandra
> Issue Type: Improvement
> Environment: C* 2.0.6 running on Ubuntu 12.04
> Reporter: Bill Joyce
> Priority: Minor
> Fix For: 2.1.x
>
>
> I've enabled tracing on my cluster and am analyzing data in the
> system_traces.sessions table. Single statement, non-prepared queries show up
> with data in the 'parameters' field like 'query=select * from tablename where
> x=1' and the request field is execute_cql3_query. But batches have null in
> the parameters field and prepared statements just have 'page size=5000' in
> the parameters field (the request field values are 'Execute batch of CQL3
> queries' and 'Execute CQL3 prepared query'). Please include the actual query
> text with prepared and batch statements. This will make performance analysis
> much easier so I can do things like sort by duration and find my most
> expensive queries.
