Initially we went for the metaphor of "what if you could keep complex SQL queries (e.g. 6-way joins and complex aggregations, the kinds of queries that today are essentially impossible outside a data warehouse) incrementally updated in your application within milliseconds? What would you build?
We're moving away from that metaphor because it seems it's more confusing than helpfuL. Tips always appreciated!
My suggestion would be consider comparing it to firebase queries. Firebase devs are already familiar with how incrementally updated queries can simplify application development a lot. But, despite Firebase's best marketing attempts, the queries are very restrictive compared to sql or datalog.
