Hi all,
I am quite new to neo4j and I try to import csv data in neo4j.
I tried the following methods :
- using load csv in neo4j in 2.1.0-M01 , 2.1.0-RC2 , 2.1.1. I use the
following request
CREATE INDEX ON :Joueur(IDJoueur);
CREATE INDEX ON :TypePaiement(Type);
USING PERIODIC COMMIT 1500
LOAD CSV FROM "file:///tmp/file.csv" AS csvLine
MERGE (joueur:Joueur { IDJoueur: csvLine[2]})
MERGE (type:TypePaiement {Type: csvLine[3]})
MERGE (type)-[:ALIMENTE{IdEvt: csvLine[0],Montant: csvLine[1]}]->(joueur);
I find that the performance is very low since the 2.1.0-RC2 release. ( 60 s
for 200 k nodes and relationships in 2.1.0-M01 , 1 hour for the same data
and request for 2.1.0-RC2 and 2.1.1 )
I don't understand this behaviour since it's on the same machine (64 go of
ram) with the same configuration.
Is someone use the new load csv in this new version without any problem on
quite big load?
- using batch importer from michael hunger with a 2.0 version. The
performance are impressive and I wonder if I can merge data in stead of
create it?
Cheers,
Frédéric
