neo4j需要多少内存来存储关系？

Question

I have a lot of nodes and relationships to store to Neo4J. I have 300k nodes and 10k different relationships types. So, let's say two nodes are linked by the 10k different relationships, I will have 3 billion relationships to store.

I wonder how many memory use one relationship in Neo4J. The relationship has no properties and its name is just a number with 6 digits max.

Any idea?

Thanks
