Just curious, since I can't find an answer anywhere (I've checked the documentation, and done reasonable due diligence with Googling third party sources).
Is there a limit to the number of nodes you can have with Cloud Spanner?
(I experimented with trying to deploy a thousand node cluster, and the console UI didn't object, the only thing that was stopping me was the hourly price tag!)
I assume at some point you enter diminishing returns ...
TIA
