Apache Arrow adapter Integration with Apache Calcite

Question

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.

Could you explain what kind of "integration" you are talking about? — Wes McKinney, Nov 28 '18 at 13:35
@wes-mckinney : we have to write all these classes [calcite-arrow-sample](https://github.com/masayuki038/calcite-arrow-sample) since its not readily available from api it self. — Ram Ghadiyaram, Nov 28 '18 at 15:30
can see [here all the classes related to api integration](https://github.com/masayuki038/calcite-arrow-sample/tree/master/src/main/scala/net/wrap_trap/calcite_arrow_sample) but not built in some one has hand written all the code for integration of arrow and calcite. — Ram Ghadiyaram, Nov 28 '18 at 16:26
all the above code was written in scala not in java. if its provided by calcite api in java many users even scala users can import and use that. — Ram Ghadiyaram, Nov 28 '18 at 16:30

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.
