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