Edward Bortnikov commented on HBASE-14921:
------------------------------------------
Indeed let's defer this discussion to the new JIRA. Not sure we have a good
definition of admissible overhead for speculative scan, but it's good to be
talking around numbers.
With this JIRA, it is our strong preference to commit ASAP (maybe this week?)
unless there is some insurmountable problem. We'll be posting a new patch soon
- please weigh in on the RB!
