godfrey he updated FLINK-20509:
-------------------------------
Description:
Currently, we use {{verifyPlan}} method to verify the plan result for both
{{RelNode}} plan and {{ExecNode}} plan, because their instances are the same.
But once the implementation of {{RelNode}} and {{ExecNode}} are separated, we
can't get {{ESTIMATED_COST}} and {{CHANGELOG_MODE}} on {{ExecNode}} plan. So in
order to make those methods more clear, we will do the following refactoring:
1. replace {{planBefore}} with {{ast}} in xml file. {{ast}} is "Abstract Syntax
Tree", corresponding to "Abstract Syntax Tree" item in the explain result;
2. remove {{planAfter}}, introduce {{optimized rel plan}} and {{optimized exec
plan}}. {{optimized rel plan}} is the optimized rel plan, and is similar to
"Optimized Physical Plan" item in the explain result. but different from
"Optimized Physical Plan", {{optimized rel plan}} can represent either
optimized logical rel plan (for rule testing) or optimized physical rel plan
(for changelog validation, etc). {{optimized exec plan}} is the optimized
execution plan, corresponding to "Optimized Execution Plan" item in the explain
result. see https://issues.apache.org/jira/browse/FLINK-20478 for more details
about explain refactor
3. keep {{verifyPlan}} method, which will print {{ast}}, {{optimized rel plan}}
and {{optimized exec plan}}.
4. add {{verifyRelPlan}} method, which will print {{ast}}, {{optimized rel
plan}}
5. add {{verifyExecPlan}} method, which will print {{ast}} and {{optimized exec
plan}}.
