[keycloak-user] Recommendation for the choice of RDBMS with keycloak

Hi, We’re looking into databases to use with Keycloak. We have been using Mongo, but Keycloak has indicated they might drop support for that. Does anyone keycloak or somebody who is using RDBMS have a strong or weak recommendation between Postgres, MySQL, and SQL Server? Keycloak seems to have good support for Postgres and MySQL, while also supporting SQL Server. Does it matter which one to choose and if yes in what manner. We might be dealing with users between 2k to 5k in a multitenant environment. Let me know the thoughts on that. Thanks Abhishek
