--------------------------------------------------------------
Note that the is a new JNI interface (to datafusion) that does not use the
c-data-interface. (and, incidentally, also takes a different approach to
packaging the native binaries in Maven than the other JNI interfaces).
See: [https://lists.apache.org/thread/6h1mry3n3fb2omf3o24dzbf0n9rhs51h] for the

Hi dev@arrow,
Recently I've created and published a Java binding[1] to datafusion[2],
as part of datafusion-contrib projects[3]. I've updated the README.md[4]
so people can pick it up via maven[5] or gradle.
Any feedback or contributions are welcome!

> [Java] Consolidate JNI compilation
> ----------------------------------
>
> Key: ARROW-15174
> URL: https://issues.apache.org/jira/browse/ARROW-15174
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Alessandro Molina
> Assignee: Larry White
> Priority: Major
> Fix For: 9.0.0
>
>
> *Umbrella ticket for consolidating Java JNI compilation initiative*
> Seems we have spread the JNI code across the {{cpp}} and {{java}}
> directories. As for other bindings (Python) we already discussed it would be
> great to consolidate and move all cpp code related to PYthon into PyArrow, we
> should do something equivalent for Java too and move all C++ code specific to
> Java into the Java project.
> At the moment there are two JNI related directories:
> * [https://github.com/apache/arrow/tree/master/java/c]
> * [https://github.com/apache/arrow/tree/master/cpp/src/jni]
> Let's also research what's the best method to build those. The {{java/c}}
> directory seems to be already integrated with the Java build process, let's
> check if that approach is something we can reuse for the {{dataset}}
> directory too
