Issue Description
I have some pyarrow vector data which is transported to java arrow flight
server.
In python arrow flight client , my code is like this:
```python
writer,reader=client.do_exchange(descriptor=pa.flight.FlightDescriptor.for_path("streamed.parquet"))
start = time()
writer.begin(schema=schema)
with writer:
while True:
pop=q.get()
if pop is None:
break
# print("send")
batch = pa.record_batch([pa.array(q.get())], schema)
writer.write_batch(batch)
```
in java arrow flight server, my code is like this:
```java
VectorSchemaRoot vectorSchemaRootReceived = null;
FieldVector v = null;
try {
while (reader.next()) {
vectorSchemaRootReceived = reader.getRoot();
// arb = unloader.getRecordBatch();
rows += vectorSchemaRootReceived.getRowCount();
v = vectorSchemaRootReceived.getVector("tensor");
}
}catch (Exception e){
e.printStackTrace();
}
```
I known arrow flight can transport Vector data type, but I want to transport
Tensor data type because I want to tansfer it into nd4j's INDArray type.
I have noticed that arrow in java does not have Tensor data type, so how can
I realize it ?
