The spec suggested a deleted node log, but we currently don't do this. This means space is lost on restarts, and might also make having an active display of firewood from an outside process difficult.

Note that the deleted node log also maps hash->root so we'd need at least parts of this for an archival storage.

Seems like having a few modes for this makes the most sense:

  • Do what we do now, which gives you best performance and loses some space on restarts
  • Write only the hash->root mappings which could be read on startup for archival data stores
  • Write that plus the "deleted" node list so that space can be fully recovered on restarts
