About Google Drive

Google Drive is Google’s cloud-storage service that allows you to store, share, and collaborate on files and folders from any mobile device, tablet, or computer. Google Drive comes with a Google Account or G Suite Account.

About the Google Drive connector

With the Google Drive connector, you can create a data source for a Google Drive file or folder. The Google Drive connector supports the following file extensions:

  • .csv
  • .tsv
  • .tab
  • .txt
  • .xslx

You can access all folders and files that you own and any folders or files that someone shares with you.

If you want to create a data source for Google Sheets, you must use the dedicated Google Sheets connector. The Google Sheets connector also supports both the selection of a specific folder or file in Google Drive. For that reason, you must enable and configure the Google Drive connector to support the Google Sheets connector.

Note

In this release, you are not able to access folders or files in a Shared Drive.

The Google Drive connector supports the following Incorta specific functionality:

Feature Supported
Directory with Union All
Encryption at Ingest
Incremental Loading
Multi-Source
Performance Optimization
Single-Source
Webhook Callbacks
Important

Google Drive supports storing files with the same name and multiple versions of the same file. The Google Drive connector supports accessing a file in My Drive that has a unique file name and current file version.

The Google Drive connector requires the following:

  • Security configurations
  • Default and Tenant Configurations

Some configurations may differ if you are deploying the Google Drive connector in an Incorta Cloud instance. For example, an Incorta Cluster in Incorta Cloud natively supports HTTPS.

Security configurations for the Google Drive connector

Security and system administrators typically address the security requirements for the Google Drive connector. The connector uses the Google API, and as such, requires the following:

  • HTTPS for the Incorta Cluster
  • G Suite account
  • Google API Project with both the Google Drive API and the Google Sheets API enabled

HTTPS for the Incorta Cluster

In order to use the Google Drive connector or Google Sheets connector, you must configure your Incorta Cluster to use HTTPS (Hypertext Transfer Protocol Secure). Typically, a System Administrator for the operating system with root access configures an Incorta Cluster for HTTPS.

Important

The Google APIs do not accept self-signed security certificates. You must use a valid certificate for a known public domain.

To learn more about how to configure HTTPS with TLS/SSL for your Incorta Cluster using Let’s Encrypt, Certbot and OpenSSL, please review Security → HTTPS for Apache Tomcat with OpenSSL.

Client Credentials

A Security Administrator or System Administrator who manages your organization’s G Suite accounts as well as your Incorta Cluster creates the required Google API project. The G Suite Account must sign in to the Google Developers Console, create a project, create an OAuth consent screen, and then create the client credentials.

To learn more about how to create client credentials for a Google API project, please review Security → Client credentials for a Google Drive API project.

Default and Tenant Configurations for the Google Drive Connector

A Cluster Management Console (CMC) administrator for your Incorta Cluster must configure each tenant to use the client credentials.

Important

After configuration, you must restart the Analytics Service, Loader Service, and any add-ons such as the Notebook Service.
