Memory config for loading data

Neo4j Graph Platform
1

Hello

I need help please

I am loading the ssb (star schema benchmark) data onto a neo4j database. For I am using the script "using period commit ...... load csv ...." from files I generated from the ssb database.

However, one of the files contains 23 million lines and it takes too long.

I have a 64GB ram virtual machine on ubuntu and I have configured my neo4j.conf as follows:

dbms.memory.heap.initial_size=40960m
dbms.memory.heap.max_size=40960m

dbms.memory.pagecache.size=20480m

I would like to know if you can give me an optimal configuration to speed up the loading.

thank you in advance

Hello @redha_benhisse1 :grinning:

For large CSV files, you should use neo4j-admin import.

Moreover, do you have unique constraints on your nodes?

Finally, you can use neo4j-admin memrec to help you configure the database memory.
