[Neo4j] Performance DB with large datasets

Hi, I'm conducting experiments with two databases and have noticed a radical performance drop when dealing with large databases. I am working with dense triadic datasets, consisting of three node types: A,B,C and hyperedges Y. Basically one hyperedge y := (a,b,c) is stored in the db as 3 neo4j rel

Hi Peter, thank you very much for your quick reply, unfortunately there is no messages.log, seems I have an older db version. I'm sending you the ls dump from the directory: total 5318580 11 active_tx_log 4096 lucene 4096 lucene-fulltext 27 neostore 9 neostore.id 34954011 neostore.nodestore

[Neo4j] Traverser optimization

Hi, I have a question regarding traverser, is there a way how I can optimize my code to use it? Problem is: my use case is a dense graph with a lot of relationships... So most of the time I have one node with thousands of relationships attached. I have tested my code on the following Graph: 1 roo

[Neo4j] Are Relationships Singleton?

Hi! I have a very stupid question... Is it ensured that a relationship between two Nodes stays a singleton, even if another relationship of the same type and direction is added between those Nodes? Sometimes I get strange results when I delete nodes, that's why I ask. Thanks in advance and best
