If google would use dgraph, should it use for everything one single dgraph DB, or for every service (Maps, YouTube, GMail...) an own dgraph DB?

thanks a lot sempai!!! some last questions ._.

what exactly do you mean with that? do you mean the own dgraph auth system? If I use multiple Clusters(=Databases??) the data within each Cluster/Database can’t interact with each other. or not??

I saw that you offer multi-tenant instancing also as an enterprise solution, that’s magnificent!! If I as an enterprise use that feature, because of multi-tenant instancing and dgraphs horizontally scaling feature, dgraph will automatically divide it into different disks, right? So that means the eggs won’t be all in the same basket, correct? But then, once again, Joins/Edges won’t work anymore between the clusters (to link user data/profiles)… right? Because e.g it was possible afaik to link Google+ stuff and YouTube together, GMail also is linked with Google Calendar (if you get an email about your flight google inserts that into your calendar), everything is linked in Googles ecosystem

I am working since years on a big project, I am building a big ecosystem too, a social network, a local eCommerce Platform, and some more stuff. I think it’s also better to use for each service an own Cluster. And then storing a copy of the user profile in every database/cluster. it ain’t that much of a problem if the user changes his email or postal address, to just perform from my backend 3 updates to each database instead of only 1 update. I think this denormalization won’t hurt, or?? or is there another/better way to manage that?

How should I start? E.g I need now 3 databases/clusters for 3 services. but multi-tenant instancing is only available for enterprises. Should I just start with 3 Shared/Dedicated plans, and then if things work good I upgrade to Enterprise level, and then I can merge everything together into a multi-tenant instancing setup? Or I can on enterprise level also just keep 3 independent ‘projects’ running, or? (btw upgrading from shared to dedicated is no problem too, or?)

thanks a lot!! sorry for this many questions .-. but don’t worry i am lurking on this forum and on the subreddit too, I’ll keep forwarding the knowledge you pass me on
