yup that's officially 10 billion atproto backlinks indexed by constellation across every lexicon that you can query at [constellation.microcosm.blue](
Hello! β€” Constellation
Constellation is a self-hosted JSON API to an atproto-wide index of PDS record back-links. You can use it to query social interactions in real time.

ok we are live! constellation can now count by many-to-many link records!! motivating example was bluemoji, but it's already usable for some general traversal. you can ask, > what issues on @Tangled have a "good-first-issue" label? check it: [Many to Many counts β€” Constell...](

this and: the big bet with microcosm is that we can bridge a *lot* of the performance gap and make client-only apps easy to build, with really acceptable performance. slingshot still needs a lot of work but it’s part of this: it can learn the graph from active users and pre-cache from the firehose RE:

Blacksky building their own implementations of atproto services is an incredibly good and forward-looking move.
[plc.wtf](https://plc.wtf ) reference mirror now has a place for PLC experiments: - [experimental.plc.wtf](https://experimental.plc.wtf ) experiment #1: upstream op forwarding. submit a PLC op and Allegedly will forward it upstream to `plc.directory` for you. everything stays in sync, but you don't have to touch the official directory at all RE:

got postgres writing 262k rows/sec so that's probably good enough for fast plc backfill for now
Finally publishing this about PLC! On a day with big PLC news!! I think the news recasts this piece into more "why that's important", and less doom hopefully! RE:

my expectations for atproto doom me to be tired by everything what’s that thing about overestimating what can be done in the short-term and underestimating the long-term
