-------------------------------
Resolution: Fixed
> Release Testing: Verify FLIP-229 Join Hints for Flink SQL Batch
> ---------------------------------------------------------------
>
> Key: FLINK-28969
> URL: https://issues.apache.org/jira/browse/FLINK-28969
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Affects Versions: 1.16.0
> Reporter: xuyang
> Assignee: lincoln lee
> Priority: Blocker
>
> Join hints for Flink SQL batch is ready. Users can define the join hint they
> want to suggest the optimizer to use the customized join strategy.
> I think we should verify:
> # Follow the doc to write a SQL with join hints and observe the final join
> strategy in the plan. The doc is preparing and you can refer this
> [pr|https://github.com/apache/flink/pull/20513] temporarily.
> # Test some unexpected behavior when writing the join hint (including but
> not limited to the conflicts on
> [doc|https://docs.google.com/document/d/19PL77ZggPIhz7FMZv2Yx7w_cnYyvmTc-mxUpJYv_934/edit#heading=h.uia01v8e78ov]
> or the [pr|https://github.com/apache/flink/pull/20513]), and observe
> whether the join strategy in the plan is expected. For example:
> ** Multi same or different args in one join hint
> ** Multi same or different join hints
> ** Multi query blocks and join hints
> ** Unknown table names in join hints
> ** Complex SQL like union, minus, correlate, filter and etc
