The difference between the task-canal and task-canal-adapter modules

[yqk123]

1.task-canal subscribes to MySQL binlog and synchronizes it to Kafka. Does this need to be persisted to MySQL? Because I see that task-canal-adapter seems to need to be persisted to MySQL. 2.What is the relationship between task-canal and task-canal-adapter, and what are the differences in their application scenarios? Is it correct that task-canal-adapter performs full synchronization, and then task-canal performs incremental synchronization? 3.Do task-canal and task-canal-adapter need to be deployed together? Can only one be deployed?
