Subject [jira] [Created] (CASSANDRA-10189) Unify read/writeUTF code paths
Date Tue, 25 Aug 2015 21:39:45 GMT
Robert Stupp created CASSANDRA-10189:
----------------------------------------

             Summary: Unify read/writeUTF code paths
                 Key: CASSANDRA-10189
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10189
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Robert Stupp
            Assignee: Robert Stupp


(Follow-up to CASSANDRA-9738 and CASSANDRA-8670)

CASSANDRA-9738 requires {{writeUTF}} functionality that has been improved in CASSANDRA-8670
plus {{readUTF}} functionality. But we need slightly different signatures - one taking {{DataInput}}/{{DataOutput}}
and one taking {{ByteBuffer}}.

We can combine both code paths and benefit from a shared, thread-local byte buffer.

Slightly different implementations are needed for array backed and direct BBs (as we can directly
access the backing array bypassing the direct BB's boundary checks).

(Part of this has already been done for CASSANDRA-9738 in {{OHCKeyCache.SerializationUtil}})
