TDB Reasoning problem for huge amount of Data

[asdas asdasd]

I want to make a huge ammount of data in TDB(about 1,000,000 records). I  was 
wondering whether I can make reasoning on that data? Forexample suppose I 
define 
rule such as "hasRelationWith(A,B) ->  willHeritage(A,B)" also I define some 
individuals like A and B and  properties such as "A hasRelationWith B" now I 
want to SPARQL to infer  willHeritage(A,B). If I want to use JENA and all the 
records in the memory, then reasoning will be awful(because it's a lot of data 
and memory is limited ). I have written this code for reasoning in TDB but it 
doesn't show any  result! So What is the problem?


    Dataset ds = TDBFactory.createDataset(directory) ;
    Model model = ds.getDefaultModel() ;
    Reasoner reasoner = ReasonerRegistry.getOWLReasoner();
    InfModel infmodel = ModelFactory.createInfModel(reasoner, model);
String qs = "PREFIX sn: 
<http://www.semanticweb.org/ontologies/2011/2/ontology1.owl#> SELECT * { sn:A 
sn:willHeritage ?o }";
Query query = QueryFactory.create(qs) ;
    QueryExecution qExec = SparqlDLExecutionFactory.create(query, infmodel) ;
    ResultSet rs = qExec.execSelect();
ResultSetFormatter.out(rs);
