Connect a warehouse

Add a connection

In the app, go to Connections → New connection, pick your provider and fill in the credentials. qontexta tests the connection right away and tells you if anything is wrong.

Supported providers

• BigQuery — upload a service-account JSON key.
• Snowflake — account, user, password.
• Databricks — server hostname, HTTP path, access token.
• PostgreSQL / Redshift — host, database, user, password.
• Oracle — host, port, service name, user, password.
• SAP HANA — host, port, user, password.

BigQuery permissions

The service account needs two roles on the project:

• BigQuery Job User (roles/bigquery.jobUser) — to run queries.
• BigQuery Data Viewer (roles/bigquery.dataViewer) — to read table schemas.

If a role is missing, the connection test will tell you exactly which one to grant.
