-------------------------------------------------------------
I was researching RDMA for Java, but seems cannot find a lot of resources, here
are the ones I can find
- https://github.com/spcl/naos (but it's under GPL 2.0):
https://www.usenix.org/conference/atc21/presentation/taranov
- https://www.ibm.com/docs/en/sdk-java-technology/8?topic=guide-exploiting-rdma
- RDMA overview:
https://www.snia.org/sites/default/files/ESF/Everything-You-Wanted-to-Know-About-RDMA-But-Were-Too-Proud-to-Ask-Final%20v2.pdf
So maybe we need to implement RDMA support using JNI (similar to libhadoop) or
Foreign Function & Memory (FFM) API (https://openjdk.org/projects/panama/) in
the higher JDKs.

> Support GPUDirectStorage
> ------------------------
>
> Key: HDDS-15353
> URL: https://issues.apache.org/jira/browse/HDDS-15353
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Major
>
> Support GPUDirectStorage (https://docs.nvidia.com/gpudirect-storage/) by
> implementing the CuObject and CuFile APIs. This requires RDMA so it might be
> very far in the future (i.e. we need might need to use or write a library
> using RDMA). There is also
> https://blogs.nvidia.com/blog/s3-compatible-ai-storage/ that implements RDMA
> on top of S3-compatible storage.
> See GDS implementation on 3FS (https://github.com/deepseek-ai/3FS/pull/407)
