Teradata PT provides four functional operator types:
Producer operators: read data from a source and write to a data stream.
Consumer operators: read from data streams and write to a data target.
Filter operators: read data from data streams, perform data filtering functions such as selection,
validation, cleansing, and condensing, and then write filtered data to data streams.
Standalone operators: perform processing that does not involve receiving data from or sending data to
the data stream.
