Subject [jira] [Commented] (PHOENIX-2715) Query Log
Date Thu, 29 Mar 2018 06:17:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16418488#comment-16418488

Sergey Soldatov commented on PHOENIX-2715:
------------------------------------------

[~ankit@apache.org] At first glance it looks reasonable. But it would be nice to test it in
real env. Could you please adopt to master branch? I tried it with HBase branch-2, but it
seems that something is wrong with my env and HBase itself doesn't work properly ( looking
into it whether it was caused by some recent commits or it's a problem on my side)

> 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.
