### Search before asking
- [X] I searched in the
[issues|https://github.com/ververica/flink-cdc-connectors/issues] and found
nothing similar.
### Motivation
Now we can support routing sharding tables into one only if they don't have a
same value of primary key. We can improve it by add two metadata columns like
`database` and `table`, and add they to a composite primary key.
You can separate it into some subtasks if needed.
