Thanks, so are both the Postgres and Scylla versions maintained in terms of new features?

I wasn't aware that AppView v1 was open source, and the most recent info I'm aware of on the topic is https://alice.bsky.sh/post/3laega7icmi2q, https://github.com/bluesky-social/atproto/discussions/2961 and https://docs.bsky.app/docs/advanced-guides/federation-archit..., and everything I've heard about Bluesky was that open source appview is "still coming".
