Provision throughput on a database in Azure Cosmos DB

This article explains how to provision throughput on a database in Azure Cosmos DB. You can provision throughput for a single container, or for a database and share the throughput among the containers within it. To learn when to use container-level and database-level throughput, see the Use cases for provisioning throughput on containers and databases article. You can provision database level throughput by using the Azure portal or Azure Cosmos DB SDKs.

Provision throughput using Azure portal

SQL (Core) API

  1. Sign in to the Azure portal.

  2. Create a new Azure Cosmos account, or select an existing Azure Cosmos account.

  3. Open the Data Explorer pane, and select New Database. Provide the following details:

    • Enter a database ID.
    • Select Provision throughput.
    • Enter a throughput (for example, 1000 RUs).
    • Select OK.

Provision throughput using Azure CLI

az cosmosdb database create --db-name

Provision throughput using PowerShell

# Create a database and provision throughput of 400 RU/s
$resourceGroupName = "myResourceGroup"
$accountName = "mycosmosaccount"
$databaseName = "database1"
$databaseResourceName = $accountName + "/sql/" + $databaseName

$databaseProperties = @{
    "resource"=@{ "id"=$databaseName };
    "options"=@{ "Throughput"= 400 }

New-AzResource -ResourceType "Microsoft.DocumentDb/databaseAccounts/apis/databases" `
    -ApiVersion "2015-04-08" -ResourceGroupName $resourceGroupName `
    -Name $databaseResourceName -PropertyObject $databaseProperties

Provision throughput using .NET SDK


You can use Cosmos SDKs for SQL API to provision throughput for all APIs. You can optionally use the following example for Cassandra API as well.

All APIs

.Net V2 SDK

//set the throughput for the database
RequestOptions options = new RequestOptions
    OfferThroughput = 500

//create the database
await client.CreateDatabaseIfNotExistsAsync(
    new Database {Id = databaseName},  

.Net V3 SDK

//create the database with throughput
string databaseName = "MyDatabaseName";
await this.cosmosClient.CreateDatabaseIfNotExistsAsync(
        id: databaseName,
        throughput: 1000);

Cassandra API

// Create a Cassandra keyspace and provision throughput of 400 RU/s
session.Execute(CREATE KEYSPACE IF NOT EXISTS myKeySpace WITH cosmosdb_provisioned_throughput=400);
