[jira] [Comment Edited] (ARROW-15174) [Java] Consolidate JNI compilation
[ https://issues.apache.org/jira/browse/ARROW-15174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17537634#comment-17537634 ]

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 archive thread.

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
