A pull that brought changes makes a link eager in that -direction, changes that came first another way make it lazy again (Plumtree's GRAFT and -PRUNE). +**writer's tree**: how a writer's changes pass on, the same on every node: from the +member list's graph and whom each member says it reaches, each member's parent is the +neighbour it reaches closest to the writer. Whoever applies a writer's change sends it +at once to its children in the writer's tree; announcements catch what the tree misses. **blob**: bytes too large for one message, fetched in chunks from several peers at once: an epoch's snapshot change (for a rejoining node) or a remake's content (for voters). |
