Dynamic task modification and online modification, aren’t these the same thing?

He might be referring to updating configuration information such as the target IP address, which requires restarting CDC.

If it’s the IP information of the target end, it will definitely restart. I’ll test it later.

The official documentation means:
Online: Modifications made while the task is running are definitely not supported.
Dynamic: You can modify the task without deleting and recreating it, just pause, modify, and resume the task.
