The Teradata Access Module for Named Pipes can be used transparently with any Teradata Parallel Transporter (Teradata PT) consumer operator through the DataConnector operator. The following figure shows how the UNIX Named Pipes Access Module communicates with Teradata PT.

Data Flow Between Teradata Access Module for Named Pipes and Teradata Parallel Transporter

Data flows through a UNIX named pipe between a writer process, such as Teradata FastExport, and Teradata PT with a consumer operator, such as Load operator, and the SQL Inserter operator, Teradata PT communicates with the Data Connector operator, which communicates with the UNIX Named Pipes Access Module.

On UNIX systems, the module supports transfer with Teradata PT through named pipes and files. Refer to the Teradata Parallel Transporter Reference (B035-2436) for more information.
