The class org.opendaylight.controller.md.sal.dom.store.impl.InMemoryDOMDataStore is deprecated in fluorine, but in this class is constructor, which have used in previous releases LogicalDatastoreType for choosing if the in-memory dataStore will have config dataTree or operational dataTree. In fluorine version, the constructor is present, but the mdsal version of InMemoryDOMDataStore is used and type is ignored. Mdsal version of InMemoryDOMDataStore is by default only with operational dataTree.

This is causing issues, when you want to have config datastore and have config false mandatory leaf, which you don't want to setup. The put operation works, but merge operation fails on preCommit phase:

The model looks as follows:

container int-node {
    list int-interface {
        key "name";
        leaf name

{             type string;         }
        leaf oper-status {
            type enumeration {
              enum up {                 value 1;                 description                   "Ready to pass packets.";               }
              enum down {                 value 2;                 description                   "The interface does not pass any packets.";               }
            }
            config false;
            mandatory true;
        }
        leaf info {            type string;        }

    }
}
