[keycloak-user] 2 Keycloak instance using the same DB.

Hello, We are trying to load balance keycloak servers to accommodate more traffic and as a failover. We are pointing 2 instances of keycloak servers(running on 2 different machines) to the same DB. Could there be a problem with that setup? If so what kind of issues are expected to come? Do we have to setup something special on the load balancer so that the sessions are maintained properly? The keycloak servers also integrates with our organization's Active Directory to defer the authentication process. Should we disable sync on one and allow ldap sync from only one server? Is there a potential problem with the same, ie 2 keycloak instance pointing to the same DB? How are other people doing loadbalancing and failover for keycloak server. Please guide. Thanks, Subhro.
