James Taylor commented on PHOENIX-2715:
---------------------------------------
FYI, we have two mechanisms that can do this already:
- Client-side metrics collection (documentation coming soon) - this is what we
use to drive our very nice internal dashboards build by [~jfernando_sfdc].
- Tracing - https://phoenix.apache.org/tracing.html

> Key: PHOENIX-2715
> URL: https://issues.apache.org/jira/browse/PHOENIX-2715
> Project: Phoenix
> Issue Type: New Feature
> Reporter: Nick Dimiduk
>
> One useful feature of other database systems is the query log. It allows the
> DBA to review the queries run, who's run them, time taken, &c. This serves
> both as an audit and also as a source of "ground truth" for performance
> optimization. For instance, which columns should be indexed. It may also
> serve as the foundation for automated performance recommendations/actions.
> What queries are being run is the first piece. Have this data tied into
> tracing results and perhaps client-side metrics (PHOENIX-1819) becomes very
> useful.
> This might take the form of clients writing data to a new system table, but
> other implementation suggestions are welcome.
