----------------------------------------


[~elserj], [~sergey.soldatov],[~chrajeshbabu32@gmail.com] can anyone help me with the review
of the attached patch.
I tried to cover as much as we discussed in the [thread|https://lists.apache.org/thread.html/89dd45a990a5f163d89433d672ca47c75e8ea86c1b21ba67d2471826@%3Cdev.phoenix.apache.org%3E]
and documented [here|https://s.apache.org/phoenix-query-log].

> 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.
