The [dphyper algorithm](https://15721.courses.cs.cmu.edu/spring2020/papers/20-optimizer2/p539-moerkotte.pdf) for join reorder has a similar structure. I'm thinking if we can adapt this algorithm (It's great!), we can also leverage the structure to represent the join graph. Also, there is my previous [implementation](https://github.com/databendlabs/databend/blob/main/src/query/sql/src/planner/optimizer/optimizers/hyper_dp/dphyp.rs#L54) -- This is an automated message from the Apache Git Service.
