Hi, I'm tring to find a way to transfer arrow data between Java and Python without memory copying, disk file writing and socket. As plasma has been removed I'm looking for a resolution in C data interface.
I went through examples here(https://arrow.apache.org/docs/python/integration/python_java.html#java-to-python-communication-using-the-c-data-interface) in arrow doc, but I can't figure out how can I create schema and data from Java side then provide it to python. I was thinking letting python provide a pointer to a writable stream/memory buffer to Java, or write data into buffer in Java then pass the address to python. But I don't know whether it's possible or not. Please let me know your opinions, many thanks!
