Importing a streams flow
Importing is a simple way to bring a streams flow from a different project or Watson Studio instance into your project. You might use importing when your streams flow needs to run in different locations.
Credentials that are needed for some operators are not imported. As a result, you might not have access to some operators that are associated with services such as Kafka.
Prerequisites
-
The Streams service that the imported streams flow needs must be installed and running. To check which instances are up and running, select My instances from the IBM Cloud Pak for Data menu, and check the instances of type streams.
-
You must have access to the downloaded streams flow file.
Procedure
To import a streams flow, follow these steps:
-
From the Projects menu, click View All Projects, and then click the name of the project to add your streams flow to. Alternatively, to create a project for the streams flow, click New project.
-
In the Project page, click the Assets tab, and then click New streams flow.
-
In the New streams flow page, click the From file, or From URL tab, and then perform the following steps:
