MappingSet is stateful, so it can't be shared between threads

    Description

      There are several instances where static MappingSet instances are used (for example NestedLoopJoinBatch and BaseSortWrapper). This causes instance reuse across threads when queries are executed concurrently. As MappingSet is a stateful class with visitor design pattern, such reuse causes invalid state.
