Hi, Inserting a DataSet of the type Row using the Flink *JDBCOutputFormat *I continuously go the warning: [DataSink (org.apache.flink.api.java.io.jdbc.JDBCOutputFormat@18be83e4) (1/4)] WARN org.apache.flink.api.java.io.jdbc.JDBCOutputFormat - Unknown column type for column 8. Best effort approach to set its value: system.
I tried to declare the Row schema by implementing the *ResultTypeQueryable* class alongside with the FlatMap function I create the final Row type for insertion but made no changes! What is this warning for?
