[keycloak-user] Using H2 database in PROD

Hello,    Are there any Strong reasons/recommendation for moving Keycloak backend from H2 database to a different database? I noticed this in the Reference guide "....you might want to use a better relational database for Keycloak like PostgreSQL"... Our application is on-premise solution and wouldn't involve with substantially large number of users. Please advise if we can go with Keycloak & H2 database for production. Best Kamal
