For CDC synchronization, do the internal modules mounter and sorter have a processing order? Does the data go through the mounter first and then the sorter?

There is another question:
Does a table pipeline only handle the data synchronization of one table, having a one-to-one relationship with the table?

Normally, it should be handed over to the Sorter for sorting, and after sorting is completed, the Mounter will parse the message.
