Queries that return multiple objects (for example iterating over storage) must be paginated.

  • Introduce RPC method chainHead_unstable_storageContinue
  • Add configurable server storage limit before starting pagination
  • Pause further storage queries for the subscription until chainHead_unstable_storageContinue is called
  • Correlated chainHead_unstable_storageContinue to resume events
