Sharded clusters and config clusters

Hello,

It’s just to know if each sharded cluster needs a config cluster? Or is only one config cluster required for all sharded clusters? Thank you.

I’m looking through the documentation and will get back to you.

However, I think it’s reasonable to believe that it’s a 1:1 connection: one sharded cluster to one config cluster. In the videos we save one database “configuration” that contained all settings. There did not appear to be a way to discern between two different sharded clusters.

Of course, there is nothing stopping you from using the same hardware to run multiple configuration clusters, for multiple sharded clusters.
