请教一下Flink，emr-flink 的flinkSQL如何只针对source表单独设置并行度呢？

请教一下Flink，emr-flink 的flinkSQL如何只针对source表单独设置并行度呢？比如kafka source表。 kafka source表如果使用全局并行度的话灵活度会很差，全局并行度比较多的话kafka-topic也没那么多分区。

Flink CDC 中flinksql开窗函数和窗口，在流任务下不支持表更新删除的source？

Flink CDC 中flinksql开窗函数和窗口，在流任务下不支持表更新删除的source，我现在所有源数据同步都是mysql-cdc和ogg，所有的数据湖表都是实时更新，有没有其他方案解决流任务下支持开窗函数和窗口呢，除非表不存在更新删除操作，是一条一条数据进入表，在流任务下开窗函数和窗口才能支持？
