Configure Bigtable in Application Design Center

Stay organized with collections Save and categorize content based on your preferences.

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 parameters you can configure when using App Design Center to create a Bigtable instance.

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
Display Name	displayName	display_name

Optional configuration parameters

The following parameters are optional. To display advanced parameters, in the Configuration area, select Show advanced fields.

Feature	Subfeature	Parameter name	Description and constraint information	Background information
Zones		Key	The zones map object key.	zones
		Zone	location	Bigtable locations
		Cluster ID	clusterID	cluster_id
		Num Nodes	serveNodes	Nodes
		KMS Key Name	kmsKeyName	Customer-managed encryption keys (CMEK)
	Autoscaling Config	Min Nodes	minServeNodes	Determine the minimum number of nodes
		Max Nodes	maxServeNodes	Determine the maximum number of nodes
		CPU Target	cpuUtilizationPercent	Determine the CPU utilization target
		Storage Target	storageUtilizationGibPerNode	Determine the storage utilization target
