[jira] [Commented] (CALCITE-2173) Sample implementation of ArrowAdapter

    [ https://issues.apache.org/jira/browse/CALCITE-2173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16836434#comment-16836434 ] 

Lai Zhou commented on CALCITE-2173:
-----------------------------------

[~masayuki038] ,are you still work on this?

What's your recent plan? I'm glad to take some time on this issue with you, 

If we have the arrow adapter, we can support vectorized udf execution ,I'd like to see the performance improvement.

> Issues:
> * Add ArrowJoin, ArrowUnion, etc..
> * This Arrow Adapter use org.apache.calcite.adapter.enumerable.PhysTypeImpl. So I have added 'of' method on PhysType to create PhysTypeImpl instance since it can't access from arrow package.
