Hi protocol friends!
I've been cooking up a Very Large PDS (vlpds) implementation capable of scaling up to billions of accounts and down to just one.
It uses Object Storage as its only state, supports HA operation, live scaling up and down, is feature-complete with the reference PDS, and is FOSS.
vlpds.jazco.dev
Overview · vlpds docs
An atproto PDS whose only durable storage is an object store. Any node serves any request, one node can run a personal server for free, and a few nodes can carry all of Bluesky's write load.
