> This ticket aims for verifying FLINK-30650: Introduce EXPLAIN PLAN_ADVICE to
> provide SQL advice.
> More details about this feature and how to use it can be found in this
> [documentation|https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/sql/explain/].
> The verification is divided into two parts:
> Part I: Verify "EXPLAIN PLAN_ADVICE" can work with different queries under
> the streaming mode, such as a single select/insert/statement set w/ or w/o
> sub-plan reuse (configured by "table.optimizer.reuse-sub-plan-enabled").
> This indicates once specifying the ExplainDetail as "PLAN_ADVICE"
> {code:sql}
> EXPLAIN PLAN_ADVICE [SELECT ... FROM ...| INSERT INTO ...| EXECUTE STATEMENT
> SET BEGIN INSERT INTO ... END]
> {code}
> You should find the output should be like the following format (note that the
> title is changed to "Optimized Physical Plan with Advice")
> {code:sql}
> == Abstract Syntax Tree ==
> ...
>
> == Optimized Physical Plan With Advice ==
> ...
>
>
> == Optimized Execution Plan ==
> ...
> {code}
> The available advice is attached at the end of "== Optimized Physical Plan
> With Advice ==", and in front of "== Optimized Execution Plan =="
> If switching to batch mode, you should find the "EXPLAIN PLAN_ADVICE" should
> throw UnsupportedOperationException as expected.
>
> Part II: Verify the advice content
> Write a group aggregate query, and enable/disable the local-global two-phase
> configuration, and test the output.
> You should find once the following configurations are enabled, you will get
> the "no available advice..." output.
> {code:java}
> table.exec.mini-batch.enabled
> table.exec.mini-batch.allow-latency
> table.exec.mini-batch.size
> table.optimizer.agg-phase-strategy {code}
