Subject [jira] [Created] (CASSANDRA-6804) Consolidate on-disk and NativeCell layouts so that reads from disk require less memory

Benedict created CASSANDRA-6804:
-----------------------------------

             Summary: Consolidate on-disk and NativeCell layouts so that reads from disk require
less memory
                 Key: CASSANDRA-6804
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6804
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Benedict
            Assignee: Benedict
             Fix For: 3.0


If the on-disk Cell representation were the same as we use for NativeCell, we could easily
allocate a NativeCell instead of a BufferCell, immediately reducing the amount of garbage
generated on reads. With further work we may also be able to reach a zero-copy allocation
as well, reducing further the read costs.
