Subject [jira] [Created] (CASSANDRA-9894) Serialize the header only once per message
Date Fri, 24 Jul 2015 14:57:04 GMT
Sylvain Lebresne created CASSANDRA-9894:
-------------------------------------------

             Summary: Serialize the header only once per message
                 Key: CASSANDRA-9894
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9894
             Project: Cassandra
          Issue Type: Sub-task
            Reporter: Sylvain Lebresne
             Fix For: 3.0 beta 1


One last improvement I'd like to do on the serialization side is that we currently serialize
the {{SerializationHeader}} for each partition. That header contains the serialized columns
in particular and for range queries, serializing that for every partition is wasted (note
that it's only a problem for the messaging protocol as for sstable we only write the header
once per sstable).
