public class TestInsertRate extends AbstractTripleStoreTestCase
The s:p:o of the statements can use random selection without replacement from a class space, a property space, and a literal space. Those spaces can be pre-populated such that we can insert up to ( #class * #prop * #value ) distinct statements if we select subjects from the class space, predicates from the property space, and objects from the literal space and the class space. However, we should also select objects from the class space, which produces additional distinct statements. The literal space should be divided into plain literals, literals with language tags, and typed literals. The space of types are the predefined XSD types plus those defined by RDFS (rdf:xml).
In order to test plain RDF insert, we do not need to do anything beyond this.
In order to test RDFS insert, there needs to be some ontology. This can be introduced by creating a class hierarchy from the class space and a property heirarchy from the property space. Such a hierarchy could be formed by either by inserting or removing rdfs:subClassOf (or rdfs:subPropertyOf) assertions from a fully connected matrix in the appropriate space.
FIXME modify to use variable length unsigned byte[] keys and the
BytesUtil.UnsignedByteArrayComparator and see how that effects performance -
the performance will be the base line on which I can then improve. Once I
have that baseline I can then go into the btree code and strip out the
polymorphic keys (except maybe int and long) and add in support for prefix
btrees and choosing short separators.
