stack commented on HBASE-5674:
------------------------------

bq. A millisecond timestamp is too heavy to carry. 

For whom?

Can you not just have your client specify timestamp of 0?

> Right now, a millisecond-level timestamp is attached to every record. 
> In our case, we only need a version number (mostly it will be just zero etc). A millisecond timestamp is too heavy to carry. We should add support to overwrite it to zero during major compaction. 
> KVs before major compaction will remain using system timestamp. And this should be configurable, so that we should not mess up if the hbase timestamp is specified by application.
