Agreed. The subscriptions really is a huge huge part of the magic, and it's a weakpoint of Kine. Thanks for chiming in.

Ideally, i'd love to see a database specific offering. Use postgres async replication (ideally somehow sharded so there's not a single consumer node) to some fan out system that's doing all the watching.

But etcd mostly does the job, seems unlikely to be going anywhere. It's be cool though.
