In the Neo4j query tuning course, we learn the Hierarchy of accessibility
But, knowing that from version 4.3 we can now create index on a relationship property and therefore I guess anchor on a relationship, is this Hierarchy of accessibility outdated?
Here is the cost of access from least expensive to most expensive:
Solved! Go to Solution.
I can see that you might simplify the hierarchy of accessibility model too.
And I'm guessing this it not the final form.
I can't wait for the new / updated query tuning course 🙂
I think, I might be wrong, node labels indexes must now be explicitly define in Neo4j 4.3.
Knowing that for a MATCH, only the anchor node will actually use labels indexes, for me this modification make sens and probably reduce the memory use by the graph. Downside is, it makes Neo4j a bit less user friendly in terms of speed when you don't know it.
But a explicit warning could be add to the browser to inform the new user.
Anyway thanks for the info.
