Flink CDC Issue Import created FLINK-34824:
----------------------------------------------
Summary: Mysql-connector cdc sourcerecord not have data type information,bug dez record have
Key: FLINK-34824
URL: https://issues.apache.org/jira/browse/FLINK-34824
Project: Flink
Issue Type: Improvement
Components: Flink CDC
Reporter: Flink CDC Issue Import
### Search before asking
- [X] I searched in the [issues|https://github.com/ververica/flink-cdc-connectors/issues] and found nothing similar.
### Motivation
when we develop streaming data platform , we also need data types to satisfied dynamic change table schema. But i fund Mysql-connector cdc record has too many useless information. I suggested to use dbz record information type to meet more needed.
### Solution
change sourcerecord code to dbz record . such as below
