> [C++][FlightRPC] Add support for alternative MemoryManagers
> -----------------------------------------------------------
>
> Key: ARROW-15374
> URL: https://issues.apache.org/jira/browse/ARROW-15374
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, FlightRPC
> Reporter: David Li
> Assignee: David Li
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We should add support for sending/receiving data using a non-standard
> allocator, given that:
> * the plan is to support UCX as a backend to Flight,
> * UCX can manage non-CPU memory,
> * the existing Device/MemoryManager API handles this case,
> We should find some way to ensure we fully reflect UCX's capabilities to
> Flight users. Furthermore, we should integrate the MemoryManager and Flight
> APIs so that Flight user code should not _have_ to worry about whether their
> backend supports this or not. (That means that for gRPC, we should do the
> copy for the user.)
> As part of this, we should extend the Flight benchmark to test this case so
> we also have a baseline.
