> 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.
