What is your actual use-cae ? Don't use rest-graphdb for performance critical things.
If you want to insert larger amounts of data, use cypher with the transactional endpoint. Either by using the http endpoint directly or by leveraging something like the jdbc-driver http://neo4j.org/develop/tools/jdbc or this experimental driver https://github.com/jakewins/neo4j_driver Later on you: You should set your heap to more (e.g. 12G) and configure your memory mapped settings according to your store files (conf/neo4j.properties) Am 21.01.2014 um 15:14 schrieb frandro <[email protected]>: > It does not make any difference. > > I'm using RestGraphDatabase as a graph db. > > There's nothing I've set. > > The environment is windows 7 x64 and i5-3570 and 16GB ram. > > 2014년 1월 20일 월요일 오전 9시 30분 55초 UTC+9, Michael Hunger 님의 말: > The problem is that you try to create one node per tx, you should try to do > 20-50k per tx. > > Then it only takes a few seconds to create 1M nodes. > > // values should be a list of 20-50k elements > > > public void createNodes(String type, String key, List<String> values) > > > > { > > Label label = DynamicLabel.label(type); > > try (Transaction tx = graphDB.beginTx()) > > { > for (String value : values) { > Node createdNode = graphDB.createNode(label); > > > > createdNode.setProperty(key, value); > > } > > tx.success(); > > } > > } > > Am 20.01.2014 um 00:31 schrieb frandro <[email protected]>: > > > Dear all, > > > > I'm just testing much work how much Neo4j can endure. > > > > I'm planning to make 1 million nodes and relations more than the nodes. > > > > I coded a method that creates a node as following and a caller to it in a > > for loop to create nodes as many as specified in the for loop. > > > > The problem is that it takes 20~30 seconds to create 1,000 nodes.
