Integration of CompletionQueue with 3rd Party Event Loop

[Caleb Epstein]

What are some suggested techniques for integrating GRPC server-side processing (i.e. CompletionQueue.Next) with another library's event model?

For example, can I get e.g. an eventfd on Linux that I can pass to epoll/select/etc to know when that a call to cq.Next will not block?

I'm interested in building some applications that will receive data from multiple channels, not all GRPC-based.  I'd like to keep processing simple and single-threaded as much as possible, so I'd like to run all of the GRPC event handlers on the same thread I'm using for my other processing.  I could "burn" a thread that sits in a loop calling cq.Next and then passing the tags over to my own processing thread, but that seems inelegant.

This is also something we are looking for.
We are using epoll and we would like to integrate grpc. Any advice?

Thanks

We do have some plans to expose this in the future, as part of the public API, but since our internal API changed and evolved much over time, and still does, we didn't want to freeze it just yet, as we don't want to force ourselves to commit to something that could still be improved.

When we are fully happy with our performance, that is most probably something that we will do.
