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

  • Άρθρο

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 subscription, create an Azure free account before you begin.

Prerequisites

  • This article requires version 2.12.1 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Sample script

Launch Azure Cloud Shell

The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.

To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.

When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.

Sign in to Azure

Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing subscriptionId with your Azure subscription ID.

If you don't have an Azure subscription, create an Azure free account before you begin.

subscription="subscriptionId" # Set Azure subscription ID here

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

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

Run the script

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.
az cosmosdb sql container throughput update Update throughput for an Azure Cosmos DB for NoSQL container.
az cosmosdb sql database throughput migrate Migrate throughput for an Azure Cosmos DB for NoSQL database.
az cosmosdb sql container throughput migrate Migrate throughput for an Azure Cosmos DB for NoSQL container.
az group delete Deletes a resource group including all nested resources.
