Because with schema-based sharding in Citus, the schemas are the sharding unit and the system can move them to new nodes being added to the cluster.

You can start with all your microservices sharing a single node, add nodes and have the storage layer distributed horizontally in a way transparent to the services themselves.

I see, so it's kinda paving the way for a db-as-a service solution?
