[keycloak-user] JTA and UserStorageProvider implementations

Hi. I'm trying to realize how should i configure our datasources from JTA point of view. As far as i know default settings (that also described in docs) don't include any JTA capabilities, so keycloak will work in local transactions mode. (There is also a thing that confused me a little: in Wildfly Admin Console all datasources have 'JTA' option enabled by default). So the question is: what settings should i use if i add UserStorageProvider implementation which uses separate DataSource. As far as i understand JTA should be enabled for such case, so how should i configure datasources. For example: - KeycloakDS [Oracle] - datasource for keycloak itself - ExternalDS [Oracle] - datasource for external user storage Should both datasource be XA and JTA capable? And what about EntityManager that i would use for user data extraction? I refer to example implementation of User Storage Provider from documentation:| | |@Stateful||(a)Local(EjbExampleUserStorageProvider.class)||public class EjbExampleUserStorageProvider implements UserStorageProvider,||        UserLookupProvider, UserRegistrationProvider, UserQueryProvider, CredentialInputUpdater, CredentialInputValidator, OnUserCache { @PersistenceContext protected EntityManager em; protected ComponentModel model; protected KeycloakSession session; public void setModel(ComponentModel model) { this.model = model; } public void setSession(KeycloakSession session) { this.session = session; } @Remove @Override public void close() {} }| || || |Does transaction context of this entity manager same as transaction context of Keycloak Session? |
