> We have been getting hit with performance problems on our time-series
> database due to invalid timestamps being inserted by the timestamp. We are
> working on adding proper checks to app server, but production performance
> could be severely impacted with significant recovery time if something slips
> past. Since timestamps are considered a fundamental part of the HBase schema
> & multiple optimizations use timestamp information, we should allow the
> option to sanity check the upper bound on the server-side in HBase.
