Bluesky’s AT protocol federation architecture diagram, which lists independent “Personal Data Server” (PDS) nodes, each with outbound arrows to a single, large, “Big Graph Service” (BGS) node. The BGS has three outbound arrows, which point to a “Labeler” node, “AppView” node, and “Feed Gen” node, respectively. The Labeler also points to the AppView and Feed Gen, and the AppView also points to the Feed Gen. Finally, the Labeler, AppView, and FeedGen all point to one of the PDS nodes.

@activitypubblueskybridge back at it again 😤
can someone with a keener eye (and maybe more experience than me) explain the difference between the AppView and Feed Gen in this blog post’s diagram?
