Bad distributed join plan: result table shard keys do not match

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. WebbDatabase sharding is the process of storing a large database across multiple machines. A single machine, or database server, can store and process only a limited amount of data.
