> Key: HBASE-11257

> Project: HBase
> Issue Type: Improvement
> Reporter: Gaurav Menghani
> Assignee: Gaurav Menghani
> Priority: Minor
>
> David and I, recently found out, when discussing the C++ client with @csliu
> from the Search Team, that we have an extraneous timestamp field in the Put.
> Actually, that field is used when we create a Put object like:
> Put p = new Put(row, ts);
> And then, if you do:
> p.add(cf, qualifier, value);
> it would use ts as a timestamp for the KeyValue for the cf, qualifier. If you
> did not specify it, it will use HConstants.LATEST_TIMESTAMP.
> One can also do this, where you explicitly state the timestamp to be used:
> p.add(cf, qualifier, ts, value)
> In either case, when the add() method is called, the KeyValue is constructed,
> and it has the proper timestamp. Therefore, once you have created the family
> map with all these KeyValues, you don't need to send the ts field provided
> during the construction. All the KVs will have the correct timestamp embedded
> by the time it will be sent across.
> This diff removes the timestamp field from the Put object. This will save us
> some network bandwidth, hopefully :)
