Pinned topic Exposing Data In HBase as RDF

‏2013-04-06T09:27:21Z |
I have only data in HBase(say student info) which is not in RDF.So I'am going though each row and converting the row into RDF and constructing an in-memory jena RDF graph which doesn't contain no more than 50 or 100 individuals(ie at any time I'am not scanning more than 50 rows from HBase).If I have an incoming SPARQL query I have to issue it against the current in-memory model and get the answer repeating the process for new batch of 50 and so on.Is this the only approach?If not how to create such a dynamic SPARQL endpoint with variable RDF store?
