Gaurav Menghani resolved HBASE-11257. ------------------------------------- Resolution: Fixed Release Note: This was completed. > [0.89-fb] Remove the timestamp from the annotation of Put > --------------------------------------------------------- > > Key: HBASE-11257 > URL: https://issues.apache.org/jira/browse/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 :) -- This message was sent by Atlassian JIRA (v6.2#6252)
