In Neo4j 4.3 index on relationship was introduced.
So I created it and run multiple queries to test if performance improved, and, unfortunately, I don't see any improvement.
In the documentation I found next line:
"Note that the index is not immediately available, but is created in the background"
So I guess index wasn't created yet.
Finally, my question is: Is there any way to found out if index was actually created and available?
