Method Detail

test_hash_join_1

public void test_hash_join_1()
                      throws Exception

 SELECT ?x ?o
 WHERE {
 
   # Turn off the query optimizer for this query so we can control the order
   # in which the BGPs will be evaluated.
   
   hint:Query hint:optimizer "None" .
 
   # Force the use of the JVM hash joins.
   hint:Query hint:nativeHashJoins "false" .
   
   ?x rdf:type foaf:Person .
 
   ?x rdfs:label ?o .
 
   # Request a hash join for the rdfs:label BGP.  
   hint:Prior hint:hashJoin "true" .
 
 }
 

A simple SELECT query with a query hint which should force the choice of a hash join for one of the predicates.

Throws:

Exception

test_hash_join_1b

public void test_hash_join_1b()
                       throws Exception

Variant on test_hash_join_1() where we force the use of the HTree.

Throws:

Exception

test_hash_join_2

public void test_hash_join_2()
                      throws Exception

 SELECT ?x ?o
 WHERE {
 
   # Turn off the query optimizer for this query so we can control the order
   # in which the BGPs will be evaluated.
   
   hint:Query hint:optimizer "None" .
 
   ?x rdf:type foaf:Person .
 
   ?x rdfs:label ?o .
 
   # Request a hash join for the rdfs:label BGP.  
   hint:Prior hint:hashJoin "true" .
   hint:Prior hint:com.bigdata.bop.IPredicate.keyOrder "PCSO" . # default is POCS
 }
 

A variant of test_hash_join_1() where a hint is used to override the SPOKeyOrder for the hash join.

Throws:

Exception
