Igor Guzenko commented on DRILL-4455:
-------------------------------------
Hi [~lpathy], we had a long discussion about the project and decided to abandon
it. Since the migration requires to rewrite a huge amount of execution-related
code and brings risks of breaking a lot of things.
> Depend on Apache Arrow for Vector and Memory

> Key: DRILL-4455
> URL: https://issues.apache.org/jira/browse/DRILL-4455
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.16.0, 1.17.0
> Reporter: Steven Phillips
> Assignee: Igor Guzenko
> Priority: Major
> Labels: doc-impacting
> Fix For: 1.18.0
>
>
> 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.
