The amount of computation required on a base update can be reduced by sharing computation and cached data between universes. We can build the dataflow graph up dynamically, extending the flow’s for a user’s universe the first time a query is executed. Implementing this as a joint partially-stateful dataflow is the key to doing this safely.
