We currently looking for a powerful query language for a distributed event sourcing system. It would have to be embeddable in rust. Is there a site where I can see more complex datalog queries and how they compare to other query languages? All the examples I have found so far were relatively trivial and basically just assumed that you knew that datalog was super powerful. A comparison of how to solve problem X, Y, Z in datalog, graphql and SQL would go a long way to convince people that it is a superior alternative.
