Add BigQuery service account as a new data source in Bigeye

  1. In Bigeye, under Catalog, click Add source
  2. Select BigQuery
  3. Input the following information
    1. Name: Alias for this data source in Bigeye
    2. Host: BigQuery host URL
    3. Timeout: default timeout for Bigeye queries
    4. Private Key File: upload the file created from the BigQuery key
    5. Target BigQuery Project ID: this is an optional field, only for advanced setup. Please see below for details.
  4. Click Validate Source
  5. Test connection: This step will query your warehouse to ensure that the user you provided has the permissions necessary to read data and run all Bigeye metric types. If an error is returned, return GCP console and ensure the service account is permissioned correctly per the above instructions.
  6. Add metrics: If test connection is successful, you will have the option to deploy Metadata Metrics on your schemas. We recommend broad coverage of these metrics across your warehouse to detect the most common data quality issues.
  7. Once you’ve added your source, Bigeye will start profiling your data to recommend autometrics. It can take up to 24 hours for this process to complete. Proceed to the Getting Started for next steps.

Advanced setup

This is only for users who want to have a service account that resides and runs queries in a different project than where the data resides. This is useful for when you want to track or limit Bigeye's BigQuery usage. Let's call the user project project-b, and the data project project-a.

First, go to project-b and follow the instructions above to create a service account. However, give it the following permissions. Copy the Service account ID here for use later.

bigquery.jobs.create
bigquery.jobs.list

Then, go to project-a, and follow the instructions above to create a role for Bigeye, but exclude the 2 jobs permissions above.

Then, go to IAM in the left navigation, click on Grant Access, and paste the Service Account ID from before in the principals text field. Add the role you created for Bigeye in the previous step to this principal. Your service account is now ready.

When you add the warehouse to Bigeye, make sure to enter project-b in the Target BigQuery Project ID field when creating the warehouse.
