Hey Anthony! I don’t know of too many other custom DB integrations besides this one: Using Redwood with Neo4j Database
At this time, and I’m guessing you know, Fauna is not supported by Prisma (yet). So you’ll have to setup your own connection, which is definitely possible. Please do start a Forum topic and keep us posted as you go – there’s a lot of interest in Fauna and I’m sure a lot of people will be curious to both help and learn from your experiment.
I know people are using Redwood currently with DigitalOcean and AWS. I haven’t heard of anyone using Azure DB or Google Cloud DB. But as long as it’s relational (and not MSQL) it is supported by Prisma.
Personally, I’m excited about MongoDB support from Prisma as I’m a big fan of the MongoDB Atlas service.
