[jira] [Commented] (HBASE-8927) Use nano time instead of mili time everywhere

    [ https://issues.apache.org/jira/browse/HBASE-8927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14104230#comment-14104230 ] 

stack commented on HBASE-8927:
------------------------------

Just read through this issue again.  [~sershe] stuff is good pushback above.

We are careful now allocating sequenceid assigning edits an order.  Should we at the same time allocate the Cell ts or at least modify the LSBs on the ts to add in some derivative of the sequenceid?  (Would only work if we've not put the edit into memstore yet).

[~cuijianwei] Didn't you suggest a few lines of code assigning a more granular ts (IIRC)?  Inside a synchronize you assigned the ts, left-shifted, and filled in lower bits with something? I can't find it just now...

> Less collisions and we are paying the price of a long anyways so might as well fill it.
