Greetings,

We are trying to achieve casual clustering where new core servers can be added and removed at scale. But, for that, we have to manually dump the customer databases and create a new core from them. Which is not a bit auto-scalable and safe. Is there a way to sync a new core server with existing core servers like when we spin a read-replica?
