>
> in [FLINK-13081|https://issues.apache.org/jira/browse/FLINK-13081], {{explain}} method will be introduced to support explain multiple-sinks plan, this issue aims to introduce {{execute}} method into {{TableEnvironment}} to trigger the program execution. and in blink planner, queries will not be optimized immediately in {{insertInto}}/{{sqlUpdate}} methods, and will be optimized together in this method.
> {code:java}
> // Triggers the program execution
> JobExecutionResult execute(String jobName) throws Exception;
> {code}
> there are two concerns about this method:
> 1. which {{execute}} methods ({{TableEnvironment#execute}} or {{StreamExecutionEnvironment#execute}}) users should use?
> 2. how to make sure users only use {{TableEnvironment#execute}} method if their code only depends on planner module instead of bridge module?
