Jacques Nadeau commented on ARROW-2892:
---------------------------------------
Arrow Java manages all memory using ArrowBuf. This would probably require:
* Enhancing The BufferAllocator and ArrowBuf to support wrapping an existing
allocated slice of memory.
* Creating an interface to expose get/put of ArrowRecordBatch.
* Some way of viewing stream information, etc.
> [Plasma] Implement interface to get Java arrow objects from Plasma

> Key: ARROW-2892
> URL: https://issues.apache.org/jira/browse/ARROW-2892
> Project: Apache Arrow
> Issue Type: Improvement
> Reporter: Philipp Moritz
> Priority: Major
>
> Currently we have a low level interface to access bytes stored in plasma from
> Java, using the JNI: [https://github.com/apache/arrow/pull/2065/]
>
> As a followup, we should implement reading (and writing) Java arrow objects
> from plasma, if possible using zero-copy.
