[keycloak-user] User REST API: n+1 selects

Hello, I'm testing KC 3.4.3 REST API and I get n+1 selects (aka 701 selects when asking for a page of 100 users). Issue 1:Looking at the code, there's n+1 select on the following fields UserEntity: - attributes- requiredActions- credentials 7The n+1 select is triggered by https://github.com/keycloak/keycloak/blob/8e53ccf5abb4d7cc3ab8d5abc9d0... This can be solved by annotated these attributes with (a)Fetch(FetchMode.SUBSELECT).I also tried using EntityGraph, but it doesn't work since we're using Collection types (instead of Set) and because we're doing pagination while fetching ToMany associations. Issue 2: n+1 select because we don't cache null values We have this select executed n times:select    resourcese0_.ID as ID1_60_0_,    resourcese0_.ALLOW_RS_REMOTE_MGMT as ALLOW_RS2_60_0_,    resourcese0_.POLICY_ENFORCE_MODE as POLICY_E3_60_0_ from    RESOURCE_SERVER resourcese0_ where    resourcese0_.ID=? This one is done here:https://github.com/keycloak/keycloak/blob/8e53ccf5abb4d7cc3ab8d5abc9... In default setup,root.realmResourceServer() is null.Since StoreFactoryCacheSession doesn't cache null values, the return value never gets cached.I don't know how to easily solve that one. Should I create an issue ? Thanks
