Julien Le Dem commented on ARROW-249:
-------------------------------------
Some requirements for the RPC layer:
- When receiving a message we need to be able to address the buffer where the
message is directly from the RPC layer without copying it.
- when sending a message, we need to be able to point to several Arrow buffers
and have them sent directly (one after the other) with no copy as well.
> [Format] Define GRPC IDL / wire protocol for messaging with Arrow data

> Issue Type: New Feature
> Components: Format
> Reporter: Wes McKinney
>
> In addition to memory maps / shared memory, we should be able to assemble one
> or more Arrow arrays in a memory block suitable for sending over the wire
> with GRPC (http://www.grpc.io/). This can be similarly adapted to other
> messaging / RPC frameworks.
> We can continue to use Flatbuffers for the metadata serialization.
