The best database for a big game?

Hello,

What would be the best database/programming language for a big game, for example a Fortnite?

I’m thinking about Mongo db or Oracle.

What I want is for it to work for many players. To give a real example 100-500 concurrent (divided into different servers), as a list of servers, where each IP, will be a game of 100 to 500 players.

Sorry for my English.

Regards.

Fortnite uses MongoDB as far as I know. We at work also use MongoDB and have about 20k CCU with ~1.5m registered users in total and it works relatively nice.
