> 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.
