They need to get rid of that email registration to download the software.

Why?

Agree it's annoying (I'm one of the co-founders) but it's the minimal 'eval' to make sure users succeed to maximize the value from their downloads. We mainly push them to slack and to share monitoring and logs with us, until they get to prod

I'm interested in the 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-...

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?

Here's a list of DPDK supported NICs:

It also means we can't automate installation of ScyllaDB.

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.

Awesome. Can't wait for the Amazon hosted version.

Note: Our new Scylla Cloud runs on AWS; it uses our Enterprise 2018 release, not the latest 3.0 Open Source. Yet would love to hear your thoughts! https://www.scylladb.com/product/scylla-cloud/

I think he's being sarcastic.

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.
