Subject [jira] [Created] (ACCUMULO-2817) Add offset and limit arguments to byte array Encoder.decode method

------------------------------------

             Summary: Add offset and limit arguments to byte array Encoder.decode method
                 Key: ACCUMULO-2817
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2817
             Project: Accumulo
          Issue Type: Improvement
          Components: client
            Reporter: Josh Elser
             Fix For: 1.7.0


Similar to ACCUMULO-2445, but presently the encoder only works on complete byte arrays. This
forces an extra copy of the data when it is located in an array that contains other information
(e.g. a composite key).

It would be nice to be able to provide offset and length arguments to {{Encoder.decode}} so
that users can avoid the additional arraycopy.

Changing to a ByteBuffer instead of byte array argument would also be acceptable, but more
churn on the API that, unless it's happening globally, I would rather avoid. It would also
incur the penalty for that extra Object, which while minimal alone, could be significant if
decoding every value in a table, for example.
