[Neo4j] Dynamic GEXF node attributes in neo4j database
Hi! Do you have any experience how to store changing attributes of node? It's like to build a table of changes for each changed node attribute. In SQL datastore quite simple, but in no-SQL? And one more question. Is it possible with some easy call though Java API how to get number of nodes and edges stored in the database? Or I have to traversal all graph? Thank you Matej Plch ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Hi Matěj, Regarding the number of nodes/edges in the database you can use the following lines of code in case you haven't deleted any (because of id re-use): *l*ong number = ((EmbeddedGraphDatabase) graphDatabaseService).getConfig().getGraphDbModule().getNodeManager().getNumberOfIdsInUse(Node.class); System.out.println(nodes number = + number); number = ((EmbeddedGraphDatabase) graphDatabaseService).getConfig().getGraphDbModule().getNodeManager().getNumberOfIdsInUse(Relationship.class); System.out.println(relationships number = + number); Cheers, Pablo On Tue, Mar 22, 2011 at 10:57 PM, Matěj Plch plchm...@fit.cvut.cz wrote: Hi!

Hi! To get the exact number you still have to count nodes/relationships. getNumberOfIdsInUse includes Id slots waiting to get reused. So the number you get may be higher than the actual number of nodes/relationships in the database. /anders 2011-03-22 23:12, Pablo Pareja skrev: Hi Matěj, Regarding the number of nodes/edges in the database you can use the following lines of code in case you haven't deleted any (because of id re-use): *l*ong number = ((EmbeddedGraphDatabase) graphDatabaseService).getConfig().getGraphDbModule().getNodeManager().getNumberOfIdsInUse(Node.class); System.out.println(nodes number = + number); number = ((EmbeddedGraphDatabase) graphDatabaseService).getConfig().getGraphDbModule().getNodeManager().getNumberOfIdsInUse(Relationship.class); System.out.println(relationships number = + number); Cheers, Pablo On Tue, Mar 22, 2011 at 10:57 PM, Matěj Plchplchm...@fit.cvut.cz wrote: Hi!
