-----------------------------------
Assignee: Larry White
> [Java] ORC JNI bridge should use the C data interface
> -----------------------------------------------------
>
> Key: ARROW-15754
> URL: https://issues.apache.org/jira/browse/ARROW-15754
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Antoine Pitrou
> Assignee: Larry White
> Priority: Major
>
> Right now the ORC JNI bridge uses some custom buffer passing which only seems
> to handle primitive arrays correctly (child array buffers and dictionaries
> are not considered):
> https://github.com/apache/arrow/blob/master/cpp/src/jni/orc/jni_wrapper.cpp#L263-L265
> Instead, it should use the C data interface, which is now implemented in Java.
