Configure Bigtable in Application Design Center

Bigtable is a key-value and wide-column store, ideal for fast access to structured, semi-structured, or unstructured data. For example, you might create a Bigtable instance to store data for the following use cases:

• Clickstream
• Internet-of-things (IoT)
• Batch analytics
• Machine learning model training

For more information, see the following:

• Bigtable overview.
• Instances, clusters, and nodes.

This document describes the connections and parameters you can configure when using App Design Center to create a Bigtable instance. The configuration parameters are based on the terraform-google-bigtable Terraform module.

Component connections

The following table includes the components that you can connect to a Bigtable instance, and the resulting updates to your application and its generated Terraform code.

Connected component	Application updates	Background information
Compute Engine instance template	The Compute Engine instances can connect to and manage the Bigtable instance. The Bigtable resource metadata information is added to the Compute Engine instance template. The roles/bigtable.admin role is added to the Compute Engine instance template service account.	Bigtable overview
Cloud Run	The Cloud Run service can perform administrative functions on the Bigtable instance. The Bigtable resource metadata information is added to the Cloud Run environment variables. The roles/bigtable.admin role is added to the Cloud Run service account.	What is Cloud Run

Required configuration parameters

If your template includes a Bigtable component, you must configure the following Bigtable instance parameters before you deploy.

Parameter name	Description and constraints	Background information
Project ID	The project where you want to deploy the Bigtable instance.	Configure components
Name	name	name
