> because multi join is a Query Graph and both equal conditions and non-equal conditions are edges in Graph. But I also think this is a longer-term problem. I prepare to do this job in 1-2 weeks. Representing the joins in a query as a JoinGraph would be very interesting. I wonder if you have an idea of where would it be done? It could be as a pass prior to the LogicalPlan: ``` sql text --> Sql AST --> JoinGraph --> LogicalPlan ``` or you could do it as part of an optimization pass, like this: ``` sql text --> Sql AST --> LogicalPlan --(optimize with JoinGraph) --> LogicalPlan ``` -- This is an automated message from the Apache Git Service.
