Warehouses

Connect Snowflake, BigQuery, Redshift, Databricks SQL, and ClickHouse.

Updated May 27, 2026

Analytical warehouses are the most common Queringo source. Most use credentials; BigQuery uses a service-account key file, and Databricks SQL uses an access token.

Steps

  1. Pick your warehouse

    From Connect source, choose your warehouse.

  2. Provide credentials or a key

    Enter credentials, or for BigQuery upload the service-account JSON key. For Databricks SQL, paste the SQL warehouse path and access token.

  3. Scope to least privilege

    Use a read-only role, warehouse, and database wherever the provider supports it.

  4. Test and discover

    Test the connection, then review the discovered schema.

For BigQuery, grant the service account read access to the datasets you want Queringo to see, then upload its JSON key in the connection form.

Troubleshooting

  • Snowflake: confirm the account identifier, warehouse, and role are correct and the warehouse can resume.
  • BigQuery: the key's service account must have read access to the datasets.
  • Databricks SQL: check the SQL warehouse HTTP path and that the token has not expired.
