LookupTransformation

Class LookupTransformation

The lookup transformation enriches the incoming data with data from the lookup source. Data from the lookup source is read into memory when the first record arrives. For each incoming row, the lookup tries to find a matching record in the loaded source data and uses this record to enrich the ingoing data.
