hi, I once read a blog about how long it take for computation operations such as read from L1 cache, RAM access, send packet from usa to eu, etc. having a rough idea of the relative cost of major computation operations, we have better control. for example, in my project i also use property to store a cityid apart from create a relationship between user to city, because if reading an int property is 10x faster than getSingleRelationship + relationship.getEndNode + cityNode.getId.
I'm wondering if could having similar list for neo4j operations. I understand some operations could be faster than another depending on different conditions. but let's only focus on basic read/write operations. below is my guess, from fastest to slowest, feel free to correct me and add more. 1, Read id of a node/relationship. 2, Read property value of a node/relationship. 3, Set property value of a node/relationship. 4, Retrieve a node/relationship by id. 5, Create a new node/relationship. 6, Retrieve a node by external id from node index. 7, Retrieve all relationships of a node. 8, Retrieve a certain subset of relationships of a node from RelationshipIndex. 9, Retrieve a certain types of relationships of a node. 10, Add a node to index. 11, Add a relationship to index. -- Best regards Linan Wang _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
