Summary: [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 :)
