Micah Kornfield created ARROW-6594:
--------------------------------------

             Summary: [Java] Support logical type encodings from Avro
                 Key: ARROW-6594
                 URL: https://issues.apache.org/jira/browse/ARROW-6594
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Java
            Reporter: Micah Kornfield


It has been posited that the Decoder object (and on-heap work in general) is potentially slow for decoding.

 

The scope of this Jira is to add a new method that instead of consuming from Decoder, consumes directly from a ByteBuffer.  In order to this we there needs to be utility classes for zig-zag decoding (one might existing in avro) from a ByteBuffer.

 

This is esentially rewriting logic in the decoder to work directly against a bytebuffer and then measure if there is a meaningful performance impact.
