  An append-only collection of compactable update batches. The Spine below is a fork of Differential Dataflow’s Spine with minimal modifications. The original Spine code is designed for incremental (via “fuel“ing) synchronous merge of in-memory batches. Persist doesn’t want compaction to block incoming writes and, in fact, may in the future elect to push the work of compaction onto another machine entirely via RPC. As a result, we abuse the Spine code as follows:
• watch
  Notifications for state changes.
