[jira] [Updated] (ARROW-6594) [Java] Support logical type encodings from Avro

["Micah Kornfield (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-6594?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Micah Kornfield updated ARROW-6594:
-----------------------------------
    Description: 
Avro supports some logical types that overlap with Arrow logical types ([http://avro.apache.org/docs/current/spec.html#Logical+Types) |http://avro.apache.org/docs/current/spec.html#Logical+Types]

 

For the ones that overlap, we should use the appropriate Arrow Logical type array instead of the raw values.

 

  was:
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.
