was (Author: zhztheplayer):
-Hi guys, would you suggest to just use the existing
*org.apache.arrow.vector.ipc.ArrowReader*? We already have a similar approach
in orc adaptor and it works fine. As schemas in Datasets API are always
predefined I think we don't have to convert the schema everytime.-

> 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.
