> [Java] Experiment with performance difference of avoiding the use of Avro
> Decoder
> ---------------------------------------------------------------------------------
>
> Key: ARROW-6593
> URL: https://issues.apache.org/jira/browse/ARROW-6593
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: Java
> Reporter: Micah Kornfield
> Priority: Major
> Labels: avro
>
> 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.
