Subject Re: DISCUSSION: lets do a developer workshop on near-term work
Date Wed, 15 Jul 2015 17:31:31 GMT

Doc:
https://docs.google.com/document/d/1LL2GAodiYi0waBz5ODGL4LDT4e_bXy8P9h6kWC05Bhw/edit#
JIRA: https://issues.apache.org/jira/browse/HBASE-14070

Covers exactly making space for local bits in the timestamps, but to
implement HLC not something 'user servicable'
