stack commented on HBASE-13379:
-------------------------------

[~jleach] What Matteo said. I tried a few variants. Need to show evidence last attempt is
good. If you have better suggestion, appreciated. Can I close this if you think it a dup of
HBASE-12148?

> I am seeing the TimeRangeTracker hotspot under heavy write load.  It looks like a good
use case for an atomic reference for the data point (min and max timestamp).  I have a working
proto, will submit patch for consideration once I run this test suite (beast).
