Flink CDC里请问flink-sql有设置source并发度为1的参数么？

Flink CDC里请问flink-sql有设置source并发度为1的参数么？其他并发大于1，没找到那个参数。 'write.tasks' = '4' ，'compaction.tasks' = '2',parallelism.default=1，是能控制source=1，'compaction.tasks' = '2','write.tasks' = '4'。但是我们是用sql文件提交的，只....

请问一下Flink，咱们这个平台怎么关闭动态调整并发度的功能？

请问一下Flink，咱们这个平台怎么关闭动态调整并发度的功能？因为我在测试环境，用的和生产环境相同的Jar包，测试环境不想调整那么放开调整那么多并发度，设置了全局并发度，好像也没控制住

大佬们Flink CDC ，addSink设置多个并发度的时候，会不会造成数据不一致啊？

Flink SQL并发度设置问题

Flink SQL中Source和sink可以通过修改connector配置实现并发度配置，而其他算子的并发度都是根据Source并发度来设置的，这样最多是128个并发度。但是有些算子做聚合等处理，128并发明显不够这个应该怎么解决呢？支持通过配置设置其他算子并发度吗？*来自志愿者整理的flink邮件归档
