--------------------------------------
Summary: [Java] Dataset JNI bridge should use the C data interface
Key: ARROW-15753
URL: https://issues.apache.org/jira/browse/ARROW-15753
Project: Apache Arrow
Issue Type: Improvement
Components: Java
Reporter: Antoine Pitrou
Right now the datasets 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/dataset/jni_wrapper.cc#L498-L500
Instead, it should use the C data interface, which is now implemented in Java.
