I asked today how to save vertex in specified cluster here
https://groups.google.com/forum/#!topic/orient-database/DTPxPBGqu5Y
Andrey politely pointed to method of OrientBaseGraph class,
addVertex(String className, String clusterName).
So, I started using it. But came up with strange (in my opinion) issue.
I create Vertex classes, that I'm going to use
private void initClasses(){
classes = new HashMap<>(IdentityType.values().length-2);
for(IdentityType type:IdentityType.values()){
if(type.name().equals("Root") || type.name().equals("Case"))
continue;
OClass clazz = graph.getVertexType(type.name());
if(clazz == null)
clazz = graph.createVertexType(type.name());
classes.put(type.name(), clazz);
}
graph.commit();
}
BTW, do I need to commit here, if graph = new OrientGraph() ?
Then, I'm adding Vertices
private void addIdentities__(List<Identity> identities){
for(Identity identity:identities){
String clusterName =
identity.getCollection().getCase().getName();
if(!db.getClusterNames().contains(clusterName.toLowerCase()))
db.addCluster(clusterName, OStorage.CLUSTER_TYPE.PHYSICAL);
Vertex v = graph.addVertex(identity.getType().name(),
clusterName);
v.setProperty(Fields.NAME, identity.getNormValue());
v.setProperty(Fields.COUNT, identity.getCount());
}
graph.commit();
}
For tests, all Vertices have class Name, this class was added at the first
place too. Cluster name is JUNIT_CASE.
After that, I try to query what I inserted
*select count(*) from cluster:JUNIT_CASE *
returns 1000000 - expected result
*select count(*) from Name*
return 0 - unexpected result
*select count(*) from V*
returns 0 - unexpected result too
Here is my schema, class Name is there

Is it a normal behavior?
If yes, point please where it's explained.
Thanks!
