- syncing should be resilient to cut connections, metadata should be persisted that
keep track of syncing state across sessions, historical syncing state should survive restart
- extra data structures to support syncing should be kept at minimum
- syncing is organized separately for chunk types (resource update v content chunk)
- syncing is organized separately for chunk types (Swarm Feed Updates v regular content chunk)
- various types of streams should have common logic abstracted
Syncing is now entirely mediated by the localstore, ie., no processes or memory leaks due to network contention.
