Configuring the Credentials

Select the account credentials which has access to relevant PostgreSQL Data Warehouse data from the dropdown menu & Click Next

Credentials not listed in dropdown ?: Click on + Add New for adding new credentials

Data Pipelines Details

Data Pipeline: Select Table/View from the dropdown
Table/View: Select a table/view from the drop-down. All tables/views which your credentials have access to should be available here. If they are not, please check the credentials selected / configured by you.
Columns: Select one or more columns from the drop-down. All columns in the selected table/view should be available here. If they are not, please check the credentials and table/view selected/configured by you.

While you can add multiple columns, the fetched table size may become too large and so it is advisable to add one columns per pipeline and use Union queries in the data warehouse to join the data for consumption
