---------------------------------------
Summary: Analyze CTE definitions at once
Key: SPARK-17590
URL: https://issues.apache.org/jira/browse/SPARK-17590
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Liang-Chi Hsieh
We substitute logical plan with CTE definitions in the analyzer rule
CTESubstitution. A CTE definition can be used in the logical plan for multiple
times, and its analyzed logical plan should be the same. We should not analyze
CTE definitions multiple times when they are reused in the query.
