I'm a bit reluctant to proceed with this PR. Spark doesn't have a cost model that we could use to estimate the benefits and costs of such materialization. That's why Spark currently materializes only multiply referenced, non-deterministic CTEs when materialization is needed for correctness. @cloud-fan, any thoughts on this? -- This is an automated message from the Apache Git Service.
