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

[abhishek raghav]

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
