### Search before asking
- [X] I searched in the
[issues|https://github.com/ververica/flink-cdc-connectors/issues] and found
nothing similar.
### Flink version
1.12
### Flink CDC version
2.1.0
### Database and its version
oracle11
### Minimal reproduce step
In Oracle with Flink CDC, one of the fields is a CLOB. When modifying a data
record, as long as the CLOB field remains unchanged, Flink CDC, during the
incremental phase, will not include the CLOB field data in the received Oracle
data updates. All other fields will be included. Only when modifying the CLOB
field data will Flink CDC transmit it. Is this a bug? Why isn’t the CLOB field
transmitted?
