alt Hacker NewsI guess the idea is to have all writes go through a central server with local read replicas for improved read perf. The default litestream sync interval is 1s. I bet many use-cases would be satisfied with a few seconds delay for cross-region notifications.
It's good for pubsub but not for claim/ack workflow unless you do If-None-Match CAS semantics on a separate filesystem which, actually, yeah that's probably fine. Feels heavy on S3 ops. But! you do save on inter-AZ networking, the Warpstream hypothesis.
