Antoine Pitrou commented on ARROW-7272:
---------------------------------------

The C data interface should be the preferred way to achieve this. It requires implementing on the Java side, though.

>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C++, Java
>            Reporter: Francois Saint-Jacques
>            Priority: Major
>
> Given a C++ std::shared_ptr<RecordBatch>, retrieve it in java as a VectorSchemaRoot class. Gandiva already offer a similar facility but with raw buffers. It would be convenient if users could call C++ that yields RecordBatch and retrieve it in a seamless fashion.
> This would remove one roadblock of using C++ dataset facility in Java.
