Concepts
Azure Cosmos DB is a globally distributed, multi-model database service provided by Microsoft Azure. It offers scalability, low latency, and high availability to meet the needs of modern cloud applications. One important aspect of optimizing the performance of your Azure Cosmos DB is configuring throughput. In this article, we will explore how to configure throughput for Azure Cosmos DB using the Azure portal.
Step 1: Navigate to the Azure portal and go to your Cosmos DB account.
In the Azure portal, locate and click on your Azure Cosmos DB account to access its settings.
Step 2: Access the “Scale & Settings” tab.
Within your Cosmos DB account overview page, click on the “Scale & Settings” tab. This tab provides access to the configuration settings for throughput.
Step 3: Choose a throughput provisioning model.
Under the “Throughput” section, you will find two options for throughput provisioning: manual and autoscale.
- Manual Provisioning: This model allows you to specify a fixed amount of throughput in terms of request units per second (RUs). You have more control over the allocated resources.
- Autoscale Provisioning: With autoscale, Azure Cosmos DB dynamically adjusts the provisioned throughput based on the workload. It automatically scales up or down the allocated resources as needed.
Step 4: Configure throughput settings.
Based on your choice in the previous step, configure the throughput settings accordingly.
For Manual Provisioning:
Select the "Fixed" or "Range" option based on your requirement.
If you choose "Fixed": Enter the desired value for throughput in RUs.
If you choose "Range": Specify the minimum and maximum range of RUs for your Cosmos DB account.
For Autoscale Provisioning:
Select the "Autoscale" option.
Specify the minimum and maximum range of RUs within which Azure Cosmos DB can automatically adjust the throughput.
Step 5: Save the throughput configuration.
Once you’ve set the desired throughput and chosen the appropriate provisioning model, click on the “Save” button to apply the changes to your Azure Cosmos DB account.
Note: Changing the throughput configuration may result in a brief period of downtime or connectivity issues during the transition. Therefore, it’s crucial to plan and schedule these changes accordingly to minimize any impact on your application.
Configuring throughput at the container level
In addition to configuring throughput at the account level, Azure Cosmos DB allows you to configure throughput at the container level. This enables you to allocate different throughputs for different containers based on their workload requirements.
Step 1: Access the “Data Explorer” tab.
In your Cosmos DB account overview page, click on the “Data Explorer” tab to view the available containers within the account.
Step 2: Select the container to configure throughput.
Locate and select the specific container for which you want to configure throughput.
Step 3: Open the “Scale & Settings” tab for the container.
Inside the container overview page, click on the “Scale & Settings” tab to access the throughput settings for the selected container.
Step 4: Configure throughput settings for the container.
Follow the same steps mentioned earlier for configuring throughput at the account level within the “Scale & Settings” tab for the container. You can choose manual or autoscale provisioning based on the workload requirements of the specific container.
Step 5: Save the throughput configuration.
After configuring the desired throughput settings for the container, click on the “Save” button to apply the changes.
By configuring throughput at the container level, you can optimize the allocation of resources for each workload, further enhancing the performance and cost-effectiveness of your Azure Cosmos DB account.
In conclusion, configuring throughput for Azure Cosmos DB is a crucial step in optimizing the performance of your database account. By using the Azure portal, you can easily configure throughput at both the account and container levels, choosing between manual and autoscale provisioning. Remember to monitor the workload and adjust the throughput settings accordingly to meet the demands of your application.

Great blog post on configuring throughput for Azure Cosmos DB! Really helped me understand the basics.
Thanks for the detailed steps. It was quite straightforward following your instructions.
Can anyone explain the difference between manual and autoscale throughput?
I set up my throughput correctly but I’m getting throttling issues. Any ideas why?
This is exactly what I needed! Thanks for the clarity.
Is autoscale throughput more expensive than manual?
I’m confused about the partitioning strategy. Any tips?
Fantastic guide. Helped me pass the DP-420 exam!
