> Refactor verifyPlan methods in TableTestBase
> --------------------------------------------
>
> Key: FLINK-20509
> URL: https://issues.apache.org/jira/browse/FLINK-20509
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Reporter: godfrey he
> Assignee: godfrey he
> Priority: Major
> Labels: pull-request-available
>
> 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}}.
