[keycloak-user] Considering removing Mongo support

[Roger Turnau (US - Advisory)]

I'd like to second Abishek's question. Long-term, I'd like to see support
for some scalable NoSQL solution -- with a slight preference for Cassandra.
Right now, I'm setting up database support for a client who prefers MS SQL
Server.

Would love to know if there are any major headaches or issues with any of
the more popular relational databases.

Thanks,

Roger Trunau
