The simulation results indicate ... WebbWe implemented consistent hash-based routing to our data services to enable more effective coalescing. For each request to our data service, we provide a routing key. For messages, this is a channel ID, so all requests for the same channel go to the same instance of the service. This routing further helps reduce the load on our database.
