> We have developed a technique that can formally be verified if two logical plans in calcite are indeed semantically equivalent. We published this paper in VLDB 2019. Here is the [link to the paper|https://www.vldb.org/pvldb/vol12/p1276-zhou.pdf].
> This technique converts two logical plan into their symbolic representations and using an SMT (Satisfiability modulo theories) solver to verify the relationship between two symbolic representations to verify the equivalence. We are wondering if it is possible that we can integrate this tool into calcite, as a way to help the correctness testing process in calcite.
