Re: [Neo4j] cant use index after commit
i followed your advice and it is now fairly good but i have a new performance issue with traversing i have this line of code Traverser travser = result.traverse(Traverser.Order.DEPTH_FIRST, StopEvaluator.END_OF_GRAPH, ReturnableEvaluator.ALL, DynamicRelationshipType.withName(name), Direction.OUTGOING); the number of nodes i traverse are on average 60 nodes , and it took me about 500 millisecond to traverse is this normal? -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/cant-use-index-after-commit-tp3233038p3247801.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Re: [Neo4j] cant use index after commit
I just created a graph like yours and run the traversal test, it takes a few
milliseconds for the initial runs but with hot caches it executes almost
instantly.

no the commit of the inner transaction is the which fails (the commit on the

i tried before using only the outer transaction before adding the node

the node deletion is the cause of the problem , this exception is thrown in
tx.finish() of the inner commit

Re: [Neo4j] cant use index after commit
ok, you can't use them both in one go that's right. so after shutting down the batch-inserter-index-provider and the batch-inserter you can use the embedded API on the same store. That's also how Neo4j-Spatial does it's two step import of openstreetmap data. First bulk load the data and then use the transactional embedded API to do some corrections / aggregations on top of that.

Hi Ahmed, if you are still having trouble, could you please provide a bare bones test case that reliably reproduces the problem? cheers, CG On Sun, Aug 7, 2011 at 6:56 PM, ahmed.elsharkasy ahmed.elshark...@gmail.com wrote: Are you sure no other reason? -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/cant-use-index-after-commit-tp3233038p3233302.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] cant use index after commit
Ahmed, please make sure not to mix BatchInserter and the normal API in the same program. Batch-Inserter does not support removal of nodes and relationships.
