Throughput (RU/s) operations with Azure CLI for a database or container for Azure Cosmos DB for NoSQL

Article
02/17/2023

APPLIES TO: NoSQL

The script in this article creates a API for NoSQL database with shared throughput and a API for NoSQL container with dedicated throughput, then updates the throughput for both the database and container. The script then migrates from standard to autoscale throughput then reads the value of the autoscale throughput after it has been migrated.

If you don't have an Azure trail subscription, create a trial subscription before you begin.

Prerequisites

You can use the local Azure CLI.

If you prefer, install the Azure CLI to run CLI reference commands.
Local Azure CLI, see how to install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
- Sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.
- When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
- Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

This article requires version 2.12.1 or later of the Azure CLI.

Note

Before you can use Azure CLI in Microsoft Azure operated by 21Vianet, please run az cloud set -n AzureChinaCloud first to change the cloud environment. If you want to switch back to Azure Public Cloud, run az cloud set -n AzureCloud again.

Sample script

Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure trail subscription, create a trial subscription before you begin.

az cloud set -n AzureChinaCloud
az login

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in.

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az cosmosdb create	Creates an Azure Cosmos DB account.
az cosmosdb sql database create	Creates an Azure Cosmos DB for NoSQL database.
az cosmosdb sql container create	Creates an Azure Cosmos DB for NoSQL container.
az cosmosdb sql database throughput update	Update throughput for an Azure Cosmos DB for NoSQL database.
