Update consistency level for an Azure Cosmos DB account with PowerShell

APPLIES TO: SQL API Cassandra API Gremlin API Table API Azure Cosmos DB API for MongoDB


This article uses the Azure Az PowerShell module, which is the recommended PowerShell module for interacting with Azure. To get started with the Az PowerShell module, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

This sample requires Azure PowerShell Az 5.4.0 or later. Run Get-Module -ListAvailable Az to see which versions are installed. If you need to install, see Install Azure PowerShell module.

Run Connect-AzAccount to sign in to Azure.

Sample script


You cannot modify regions and change other Cosmos account properties in the same operation. These must be done as two separate operations.


This sample demonstrates using a SQL API account. To use this sample for other APIs, copy the related properties and apply to your API-specific script.

# Reference: Az.CosmosDB | https://docs.microsoft.com/powershell/module/az.cosmosdb
# --------------------------------------------------
# Purpose
# Update Cosmos DB account: Change default consistency level
# --------------------------------------------------
# Variables - ***** SUBSTITUTE YOUR VALUES *****
$resourceGroupName = "myResourceGroup" # Resource Group must already exist
$accountName = "myaccount" # Must be all lower case
$consistencyLevel = "BoundedStaleness"
$maxStalenessInterval = 300
$maxStalenessPrefix = 100000
# --------------------------------------------------

# Get existing Cosmos DB account
$account = Get-AzCosmosDBAccount -ResourceGroupName $resourceGroupName -Name $accountName

Write-Host "Updating account $accountName"
Update-AzCosmosDBAccount -InputObject $account `
    -DefaultConsistencyLevel $consistencyLevel `
    -MaxStalenessIntervalInSeconds $maxStalenessInterval `
    -MaxStalenessPrefix $maxStalenessPrefix

Clean up deployment

After the script sample has been run, the following command can be used to remove the resource group and all resources associated with it.

Remove-AzResourceGroup -ResourceGroupName "myResourceGroup"
