Wes McKinney commented on DRILL-4455:
-------------------------------------
Great. Arrow has some departures from Drill's ValueVectors, like using 1 bit
for validity instead of 1 byte, but otherwise I don't think it would be too
difficult to "cast" from one to the other. Obviously it would be great for
Drill to use Arrow natively at some point

> Key: DRILL-4455
> URL: https://issues.apache.org/jira/browse/DRILL-4455
> Project: Apache Drill
> Issue Type: Improvement
> Reporter: Steven Phillips
> Assignee: Steven Phillips
> Priority: Major
> Fix For: Future
>
>
> The code for value vectors and memory has been split and contributed to the
> apache arrow repository. In order to help this project advance, Drill should
> depend on the arrow project instead of internal value vector code.
> This change will require recompiling any external code, such as UDFs and
> StoragePlugins. The changes will mainly just involve renaming the classes to
> the org.apache.arrow namespace.
