Q:

Apache Arrow adapter Integration with Apache Calcite

Is there any option readily available to integrate apache arrow and apache calcite? 
I observed that CSV, JSON has this integration feature. but Apache Arrow doesn't have this.
we have to write all these classes like calcite-arrow-sample since its not readily available from api it self.

A:

After extensive research, found that This feature is not readily available as of today and have to write the code following calcite-arrow-sample
. I wrote this feature in java emulating the code features in above link.
