问题 I have the following APOC trigger which contains a apoc procedure. This works as desired but I am wondering if I used a lot of WITH statements, is that the way to go? or is there a better way to refactor this code. I am still new to neo4j so not sure. The control flow- Whenever the Enrollment node is created, it creates an SPerson node and depending on the size(number of SPerson nodes) it creates an enrolled or waitlist(if size>3, and deletes enrolled relation) relation with the course node.
