Reading Tensor from Plasma in Java

[Clive Cox <cc...@seldon.io>]

I want to read an Arrow Tensor saved from python to Plasma into Java.
I thought it might be directly saved as a Tensor Flatbuffer but it looks
like not. Can someone say how this can be done or the FlatBuffers type to
use on the returned bytes from Plasma?

Thanks,

Clive

I'd suggest taking a look at how the custom TF op reads from the plasma
store
https://github.com/apache/arrow/blob/d7b6ca7feb8f6419cee7069dcef20252579ea107/python/pyarrow/tensorflow/plasma_op.cc#L238
.

You can directly read the object using the Java Plasma client (and then
create a TF Tensor from the resulting buffer). It may also be possible to
use the custom TF op in Java though I'm not sure what's involved there.
