bnodes mapping in JenaGraphAdaptor should not keep growing with every parsing
of rdf files
------------------------------------------------------------------------------------------
Key: CLEREZZA-395
URL: https://issues.apache.org/jira/browse/CLEREZZA-395
Project: Clerezza
Issue Type: Improvement
Reporter: Hasan
With every parsing of rdf files free memory is getting less.
The problem seems to lie in the JenaGraphAdaptor class
It has a member:
final BidiMap<BNode, Node> tria2JenaBNodes = new BidiMapImpl<BNode, Node>();
which grows each time a serialized graph get parsed.
My experiments with my test data show
At the end of the 1st parsing: Size of tria2JenaBNodes = 87200
At the end of the 2nd parsing: Size of tria2JenaBNodes = 130800
At the end of the 3rd parsing: Size of tria2JenaBNodes = 174400
