You can add connections to a broad array of services (data sources) in projects and catalogs. Source connections can only be used to read data; target connections can only be used to load (save) data. When you create a target connection, be sure to use credentials that have Write permission or you won’t be able to save data to the target.
Not all connections are available for all Watson Studio and Watson Knowledge Catalog plans.
From a project, you must create a connection to a data source before you can read data from it or load data to it.
From a catalog, you must add a connection asset before you can add data assets for the tables you can access from the connection.
Note: This topic does not apply to streams flows. See Creating a connection in a streams flow.

The connection to Google BigQuery requires the following BigQuery permissions:
The predefined BigQuery Cloud IAM role
bigquery.adminincludes these permissions. Otherwise, a combination of two roles is needed. One role from each column in the following table.
First role Second role

Before you configure the connection, you’ll need to set up API3 credentials for your Looker instance. See instructions at Looker API Authentication.
- Microsoft Azure Data Lake Store
Before you configure the connection, you must create an Azure Active Directory (Azure AD) web application, get an application ID, authentication key, and a tenant ID. Then you must assign the Azure AD application to the Azure Data Lake Store account file or folder. Follow Steps 1, 2, and 3 at Service-to-service authentication with Data Lake Store using Azure Active Directory.
