Subject Re: Using 'zero copy' for interop with python from java
Date Sat, 06 Jun 2020 04:00:43 GMT

Hi there,

I’m coming here from clojure, where we are hoping to use more of Arrow for https://github.com/clj-python/libpython-clj
<https://github.com/clj-python/libpython-clj>, a library that gives very easy python
interop from the JVM.

Here is the link to the initial question:
https://clojurians.zulipchat.com/#narrow/stream/151924-data-science/topic/dplyr-like.20API.20to.20tech.2Eml.2Edataset/near/199914955

The use case would be to load from a database on the Java side and then convert it to arrow,
allowing it to be consumed by a python ml library (with the whole zero copy thing). 

Once there is a Java Arrow Object created in the JVM, how would it be accessible by the Python
Library?

I was hoping to get some input or a simple example on how it might be done

Chris.
