BigQuery

The integrated Google Cloud service offers a scalable, high-performance relational database that operates serverlessly.

Supported Methods

Means for Lumi to connect to the client to implement the services required:

• Direct

  The default / typical connection option. Interfaces directly with the target system over the Internet with no mediation. Suitable for most cloud-hosted scenarios or public-facing resources. See Network Configuration for more details.

• Gateway An alternative connection method leveraging a Lumi AI Data Gateway. This uses Lumi AI's purpose-built connection agent to mediate communications. Ideal for restricting access to systems within a protected network. For more information, see Data Gateway.

Supported Limits

The following are limitations that can be set to fine tune the agents' actions:

• Cost Limit Before running a query, if the system supports it, the system-specific compute cost (or surrogate) estimate will be processed and compared to an organization-level/admin-set cost limit for systems of this type (if configured/set). If exceeded, the query will not run (and either the workflow will attempt an optimization or the user will be notified).

• Duration Limit An alternative to cost, queries will be stopped the system supports a duration/timeout limit and one is set/configured at the organization level (across systems).

Available Parameters

These properties are the essential source system connection properties that all queries are directed towards.

* Required parameters

Project ID*

The unique identifier for the Google Cloud project which consists of lowercase letters, digits, and/or hyphens while starting with a letter.

How To Obtain Project ID

Service Account Credentials*

Credentials obtained from the Google BigQuery API interface to allow Lumi to access the database. The credentials should be a JSON key file containing the private keys and other information needed.

How to Get Credentials

System Permissions & Configuration

To ensure proper access and functionality, please follow these recommended steps:

• Create a Service Account: Proceed with this step if you have not already established a service account.

  • For guidance, see How to Generate A Service Account.

• Assign Roles: The following permissions need to be assigned to the associated Service account.

  • BigQuery Data Viewer: Grants permission to view tables.

  • BigQuery Job User: Allows for the execution of queries.

Special Considerations

No noteworthy considerations.

Common Issues

• Ensure BigQuery API is enabled for the project

• Ensure the generated service has its required roles
