I haven been using GenerateTableFetch to get data from Database. By default Nifi will Convert all data to Avro format (I set Use Avro Logical Types = true), then I apply ConvertAvroToORC processor to get the final result. But all datatypes which are different from int or string will be converted to binary. Is there any ways I can get exact data type from source.
I already tried to convert them all to string (Use Avro Logical Types = false) but it seems not the right way to go.
