I'm interested in the http://seastar.io/ http://seastar.io/ networking library that the Scylla guys built. Looks like it runs on DPDK and might be a nice way to do user mode networking. Anyone tried using it in other projects?

Yep! Talk to Kefu Chai at RedHat. He's using Seastar to rebuild Ceph. Here's his presentation from Scylla Summit 2018 back last October: https://www.scylladb.com/tech-talk/redhat-on-rebuilding-the-ceph-distributed-storage-solution-with-seastar/ https://www.scylladb.com/tech-talk/redhat-on-rebuilding-the-...

  Do you need to have a certain network card for DPDK to work? Can I just rent a random dedicated server, install DPDK and get userland networking?

I've also been interested in this project. Several years ago, I was toying with the idea of building a Kafka-compatible broker implementation with it. Although I didn't get very far, it's a very powerful and well-designed framework.

  i have a prototype of that same idea working w/ seastar.

If you are thinking about starting a Seastar project, definitely check out SMF [0]. It's a highly optimized RPC framework that uses Seastar, and makes it easy to build high-performance servers and clients. Seastar itself is RPC agnostic, and this project has a great implementation of functionality most developers will eventually need. [0]: https://github.com/smfrpc/smf https://github.com/smfrpc/smf
