org.apache.flink.api.java.typeutils.TypeExtractor [] - Class class com.starrocks.connector.flink.table.sink.StarRocksSinkRowDataWithMeta cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance and schema evolution.
