Subject [jira] [Created] (HBASE-5021) Enforce upper bound on timestamp
Date Wed, 14 Dec 2011 09:52:31 GMT
Enforce upper bound on timestamp

                 Key: HBASE-5021
                 URL: https://issues.apache.org/jira/browse/HBASE-5021
             Project: HBase
          Issue Type: Improvement
            Reporter: Nicolas Spiegelberg
            Assignee: Nicolas Spiegelberg
            Priority: Critical
             Fix For: 0.94.0

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.
