在我提交的flink-cdc-mysql的任务中，需要flink同步多张表的数据，但是我遇到了server-id重复的问题。我尝试过设置随机数，但是server-id有一定的取值范围，并且随机数还是有可能重复。官方文档建议我将server-id设置为一个范围，比如5400-6400，并且设置flink的并行度。这些我都做了，但是当我同步表的数量较多时，还是会出现server-id重复的问题导致任务提交失败。我需要如何设置才能如何避免这种错误？
In the Flinks-cdc-mysql task I submitted, flink was required to synchronize
data of multiple tables, but I encountered the problem of server-id
duplication. I tried to set a random number, but server-id has a range of
values, and random numbers can be repeated. The official documentation advised
me to set server-id to a range, such as 5400-6400, and set flink's parallelism.
I did all of this, but when I synchronized a large number of tables, I still
had the problem of server-id duplication, which caused the task submission to
fail. What do I need to set up to avoid this error?
