Some thoughts:

Linkedin just deprecated Kafka in favor of Northguard [1]. Curious how this actually compares in practice. Is it worth the effort of building yet another distributed log? Is it worth the effort to mantain Kafka if new alternatives are popping? Jepsen found plenty of issues last year [2], so maybe Linkedin is in the right direction by building from scratch...

Distributed systems are tough to get right, and while it's exciting to see new approaches, the space is definitely getting harder to follow.

I'm a big fan of https://nats.io/ as a lightweight alternative to Kafka. I think of it like Nomad vs. Kubernetes: you can get 80% of the functionality for the cost of 25% of the complexity.

It is impossible to know what Northguard can and cannot do since it's an internal products.
