[Java] Experiment with performance difference of avoiding the use of Avro Decoder #281

Open asfimport opened 5 years ago

asfimport commented 5 years ago

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.
