[keycloak-user] h2 for production

Hi, I understand that it is not recommened to use h2 as your production database format. However, reading this: http://stackoverflow.com/questions/12064030/are-there-any-reasons-why-h2-... and given our situation (small userbase, no heavy use, no cluster / replication, no HA, etc, etc) is choosing h2 really a bad idea? Could we, for example, run into problems with keycloak updates? MJ
