`cargo build` failed about rdma-sys

[pwang7]

Currently, tikv only support grpc, I am investigating whether it is feasible to replace grpc with tonic and integrate RDMA to support dual stack. Welcome to comment on it, thanks.

I think it's doable. TensorFlow already has its network support gRPC over RDMA, but it's not for general gRPC. Tonic has some adapter to support different underlying network layer.

Hi, thanks for the reporting it @microyahoo.

This is a simple issue, would you please kindly fix it?

[microyahoo]

Are these libraries (rdma-sys and async-rdma) currently used in production environment? Is it still being maintained? I am currently investigating the rmda solutions.

[pwang7]

yes, it's under development, rdma-sys is just a Rust wrapper to ibverbs, async-rdma is to leverage Rust async to provide a better RDMA API.

Thanks for your reply. I noticed that there is very little documentation related to the repo right now. Are there any plans to improve the documentation?
In addition, I have submiited a PR, PTAL.

This RDMA Rust project is still working in progress, once it's stabled, we'll definitely add more documentation.

BTW, I fixed the build failure, also upgrade bindgen #11, let me know if nay further issue.

BTW, may I ask what kind of scenario would you like to apply RDMA to?

Yes, I have noticed the discussion of tensorflow.
In addition, tonic already supports other transports than h2/tcp through Endpoint::connect_with_connector and Server::serve_with_incoming.
Thanks for your advice.
