Introduction
In this article, we show you how to connect your Astrato workspace to Amazon Redshift. It's designed to be a quick process and easy to follow.
Connection data required
When setting up your data connection, you'll need to know:
Data connection: Hostname, Port
Database Credentials: User name, Password
SSL Credentials: SSL mode - default set at 'Disable' - please amend as required to meet your organization's security policy.
Access to information schema- To build a data model, the user in the data connection must have read access to the Information_schema.
To validate access, run this query and confirm that you get the list of schemas in the database you are connected to. Replace %s in the code below with the database name.SELECT schema_name
FROM information_schema.schemata
WHERE schema_name !~ '^pg_' AND schema_name <> 'information_schema' AND catalog_name = '%s'
ORDER BY LOWER(schema_name) ;`
