Does the relay durably store data from the PDSes it crawls? I thought it just aggregates and distributes data from the PDSes it is actively connected to. Edit:

Edit: I now see via https://docs.bsky.app/docs/advanced-guides/backfill https://docs.bsky.app/docs/advanced-guides/backfill that this is the case. I'm surprised that the docs don't mention it more clearly that relays store the full contents of the attached PDSes, but maybe I'm just not up to speed on learning how this works.
- steveklabnik 2y agoCurrently the relay stores the entire history. That’s why people are saying that it’s a centralization point that’s unlikely to be able to be hosted by others as the network grows. That said the team is aware of this and has ideas for how more limited subsets could work. That’s more important as time goes on, so this is yet another one of those prioritization related issues where improvements will happen, but it’s also good to know about the current state of things too.
