save method of CRUDRepository is very slow?

Question

i want to store some data in my neo4j database. i use spring-data-neo4j for that.

my code is like the follow:

    for (int i = 0; i < newRisks.siz         


        

Answer 1

I think I've found a solution:

I tried the same insert using the nativ neo4j java API:

GraphDatabaseService graphDb;
Node firstNode;
Node secondNode;
Relationship relationship;

graphDb = new EmbeddedGraphDatabase(DB_PATH);
Transaction tx = graphDb.beginTx();

try {
    firstNode = graphDb.createNode();
    firstNode.setProperty( "name", "Root" );

    for (int i = 0; i < 60000; i++) {
        secondNode = graphDb.createNode();
        secondNode.setProperty( "name", "risk " + (i+1));

        relationship = firstNode.createRelationshipTo( secondNode, RelTypes.CHILD );
    }
    tx.success();
}
finally {
    tx.finish();
    graphDb.shutdown();
}

the result: after some sconds, the database is filled with risks.

Maybe the reflections slow down this routine with spring-data-neo4j. @Michael Hunger says somthing like that in his book GoodRelationships, thanks for that tip.
