      Description

      When the same bit of processed data is used in multiple places (within the query to begin with), it should be materialized. Some use cases are grouping set queries where one group computation can be derived from other group computation, with clause, data mining like queries and graph processing queries. To begin with, the materialized data could be scoped for the query. But this has the potential to grow to a group of queries.
