1. 1. 1. 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?
