BigQuery
This page contains the setup guide and reference information for the Big Query source connector.
#
To Connect with BigQuery
- A Google Cloud Project with BigQuery enabled
- A Google Cloud Service Account with the "BigQuery User" and "BigQuery Data Editor" roles in your GCP project
- A Service Account Key to authenticate into your Service Account
#
Getting Started
In order to use bigquery in our system, first you need to enable bigquery in your Google cloud project. Next, you need to create a Service account with the "BigQuery User" and "BigQuery Data Editor" roles, which grants permissions to run BigQuery jobs, write to BigQuery Datasets, and read table metadata. However, you can use a pre-existing Service Account if you already have one with the correct permissions.
The easiest way to create a Service Account is to follow GCP's guide for Creating a Service Account. Once you've created the Service Account, make sure to keep its ID handy as you will need to reference it when granting roles. Service Account IDs typically take the form
<account-name>@<project-name>.iam.gserviceaccount.com
Then, add the service account as a Member in your Google Cloud Project with the "BigQuery User" role. To do this, follow the instructions for Granting Access in the Google documentation. The email address of the member you are adding is the same as the Service Account ID you just created.

Service Account keys
Service Account Keys are used to authenticate as Google Service Accounts. You'll need to provide its Service Account Keys. See the Google documentation for more information about Keys.
Follow the Creating and Managing Service Account Keys guide to create a key. We currently support JSON Keys only, so make sure you create your key in that format. As soon as you created the key, make sure to download it, as that is the only time Google will allow you to see its contents. Once you've successfully configured BigQuery as a Datasource, delete this key from your computer.
