IBM InfoSphere Streams bridge reference

About this bridge

The IBM InfoSphere Streams bridge imports endpoints from endpoint description files that are exported from InfoSphere® Streams. After you import the endpoints into the metadata repository, you can use the endpoints in InfoSphere DataStage® and QualityStage® jobs.

Each endpoint contains one top-level tuple. Tuples can contain other tuples and tuple attributes. Tuple attributes are the equivalent of column definitions.

To use the imported endpoints in a job, on the Input or Output tab of a Streams Connector stage in the job, click Configure. You can select from a list of source or target endpoints that are stored in the metadata repository.

You can move endpoints between different installations by using the istool command line. For example, you could move endpoints from a development environment to a production environment.

The IBM InfoSphere Streams bridge is installed on the services tier. It is automatically available on any metadata interchange server that you create in InfoSphere Metadata Asset Manager.

Prerequisites

In InfoSphere Streams, use the command-line tool generate-ds-endpoint-defs to export an endpoint description file that contains the endpoints that you want to import. FTP the file to the local computer from which you run the import.
