Really? Would have helped to check out: https://opensource.org/licenses/alphabetical All the licenses(Except the Third-Party Driver licenses) look opensource to me.

What the heck? You are right, AGPL is listed, yet clearly violates https://opensource.org/osd-annotated definition. Could somebody explain this to me?

It conforms with OSD for the same reason GPL v2/v3 does. As I understand it, AGPL simply treats "networked access" as a subset of "linking".

There's a ton of legal grey area that hasn't been tested or has been hand waved away (do I have to open source my web application if it connects to a database that is AGPL licensed?)

There is no clear violation, AGPL is a copyleft license based on the GPL v2 (one of the most prominent OSS licenses) but closes the application service provider loophole.

Open Source Software (OSS) ensures users have access and can freely modify source code for software they use which the AGPL does, it’s even even more copyleft than the GPL as it ensures modifications to software by ASPs are also made available.

As for mangodb, I still qualify this as open source. I don't care about what OSI says. For me as long as I can read the source, and modify it for my business, it's fine. It doesn't need to be free as in free beer.

Well that's exactly the issue...you can't modify it or use it for your business if you compete with Mongo corp

I thought I could modify as long as I either pay or give money to mongodb?

If you are interested in our CEO's take on the Mongo SSPL, we published this blog a few months ago.

Michael from MongoDB here again. MongoDB Community is still free to view, download, modify, etc. The SSPL change affects no-one besides those offering the licensed software (MongoDB) as a public service.

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:

Congrats to the Scylla team! These features and performance improvements are pretty huge for people working with Apache C* that want to evaluate Scylla. Compatible storage formats will certainly make evaluations much easier. Also, hope the Scylla experience with MVs is better...

As far as compatibility w/ Apache Cassandra 3.x+, is there anything outstanding?
