   I can make my implementation public [AcyclicJoin 
Node](https://github.com/LorrensP-2158466/AcyclicJoinNode). In short, it 
introduces a new logical node (acyclic join) that is coupled with a physical 
node (join impl of that acyclic join), but the physical node is part of that 
PhD project, which I can't share. To create those acyclic join nodes, I had to 
detect if a particular join tree (i.e. subsequent joins in a LogicalPlan) is 
acyclic or not.
   
   I also think adding an example of SQL analysis would be nice. I'll move to 
#10871 so this can be closed.
