Thanks for the clarification. Still I would think it is sub-optimal to split shards when we actually don't know which mailboxes we actually split. It may create splits of small users which leads to unnecessary distribution of the smaller users.
We thought about doing the routing ourself. As far as a I understood we can do distributed searches across multiple collections. What do you think about this option ? For the ideal solution: when will custom routers be supported ?
