Gary Helmling commented on HBASE-8927:
--------------------------------------
Regarding precision, FWIW in the case of Tephra, we multiply the current
timestamp in milliseconds by 1000000 and add a counter (reset every
millisecond). 1 billion operations per seconds is probably more than we need,
so if we need to support more that 292 years worth of timestamped values, we
could probably adjust to a lower counter range.
> Use nano time instead of mili time everywhere
