> Hi, I want to get job's execution plan in Flink SQL 1.11, but i meet exception "No operators defined in streaming topology. Cannot execute." when use `env.getExecutionPlan()`. The same code runs fine in Flink SQL 1.10. I found translation operations only happen when StatementSet.execute() is called in Flink SQL 1.11. So we cannot get job's execution plan before the job submit? Can we support to get execution plan in `StatementSet` or invoke method `TableEnvironmentImpl#translate` in `StatementSetImpl#addInsertSql`? I think the latter is better so that we can reuse `env.getExecutionPlan()`.
