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.
> [C++][Java] JNI bridge between RecordBatch and VectorSchemaRoot
> ---------------------------------------------------------------
>
> Key: ARROW-7272
> URL: https://issues.apache.org/jira/browse/ARROW-7272
> 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.
