flinksql bug：doesn‘t support consuming update and delete changes which is produced by

org.apache.flink.table.api.TableException: StreamPhysicalOverAggregate doesn’t support consuming update and delete changes which is produced by node Join(joinType=[InnerJoin], where=[(wms_bill_id = wms_bill_id0)], select=[service_type, org_id, create_time, update_time, wms_bill_id, unique_code, wms_bill_id0], leftInputSpec=[NoUniqueKey], rightInputSpec=[NoUniqueKey])

这个报错有效的部分是：StreamPhysicalOverAggregate doesn’t support consuming update and delete changes which is produced by node Join
这句话有两个变量 一个是 StreamPhysicalOverAggregate 另一个是 node Join
表示 前一个算子 因为 后一个算子 而不支持更新和删除操作，简单点说就是 这个代码不支持回撤流场景，

只需要分析 StreamPhysicalOverAggregate 是哪里出现，这是个聚合函数。
另一个分析 node Join 是join的部分
从我个人的代码中 我分析出，回撤流场景ÿ
