Thanks for reply.
Do you mean that every time I should delete nodes/relationship from that
only query graph instance and insert new nodes/relationship to that? By
deleting the nodes/relationship query graph instance cache would be empty?
Right now, I've used the following solution and it's really better.
However, still it has small memory leakage.
smallGraph = new GraphDatabaseFactory().newEmbeddedDatabaseBuilder(graphPath)
*.setConfig(GraphDatabaseSettings.pagecache_memory,
"240k")*.newGraphDatabase();
Thanks anyway
Best.
