Plasma Java API to read RecordBatch from Python process

[Ji eun Jang]

Dear Arrow developers,

I am a new Arrow user and need some help on Plasma Java API. (I am using 
compiled library from github repo, not the release 0.9.0).

I am trying to move data between two processes (one in Java and the 
other in Python). I was able to do it through sockets using Java 
ArrowStreamReader/Writer and Python RecordBatchStreamReader/Writer.

Now I want to explore the Plasma option. I was able to use Plasma 
storage using PlasmaBuffer within Python, as shown in 
https://arrow.apache.org/docs/python/plasma.html.

Do we have  an equivalent API in Java? Could you please point me to an 
example, if exists, showing how to read/write record batches from/to 
Plasma storage in Java?

Thank you,

Jieun
