> Key: CALCITE-3913
> URL: https://issues.apache.org/jira/browse/CALCITE-3913
> Project: Calcite
> Issue Type: Wish
> Reporter: Qi Zhou
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h

> 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.
