*Background:*
Consume sub-database and sub-table data through regular expressions, scan.startup.mode=initial

*Phenomenon:*
1. The task occurs during the snapshot data synchronization phase;
2. After the task runs normally for a period of time, no more data will be read. In fact, there is still a lot of data in the upstream Mysql table;
3. When the task is restarted from the state, it will read normally for a period of time and then stop reading.
