--------------------------------------
Summary: [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
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.
