Use the following steps to use the emulator on Linux or macOS environments:
- Run the following command from the Windows virtual machine and make a note of the IPv4 address: Bash Copy ipconfig.exe
- Within your application, change the endpoint URL to use the IPv4 address returned by ipconfig.exe instead of localhost.
- From the Windows VM, launch the Azure Cosmos DB Emulator from the command line using the following options. ...

Where does Cosmos DB store data?
Internally, Cosmos DB stores "items" in "containers", with these two concepts being surfaced differently depending on the API used (these would be "documents" in "collections" when using the MongoDB-compatible API, for example). Containers are grouped in "databases", which are analogous to namespaces above containers.
How To Start Cosmos DB Emulator - Azure Lessons
Here, we will discuss How To Start Cosmos DB Emulator, Cosmos DB Emulator Linux, Cosmos DB Emulator Download Windows 10, Cosmos DB Local Emulator, etc.
Use the Azure Cosmos DB Emulator for Development and Testing - GitHub
Differences between the Cosmos DB Emulator and Azure Cosmos DB. Because the Cosmos DB Emulator provides an emulated environment running on a local developer workstation, there are some differences in functionality between the emulator and an Azure Cosmos DB account in the cloud:
Getting started with Azure Cosmos DB - end to end example
Understand how to create your first Azure Cosmos DB implementation with this two-part series. From when and why to choose a NoSQL database to creating containers and selecting an API, follow this end-to-end example to walk through the steps you'll take to get started.
Issue #17 · Azure/azure-cosmos-db-emulator-docker - GitHub
No, we do not use Azure DevOps. We use Docker (Linux) inside of Azure Container Instances. The reason we want to use the emulator is that we probably want to support thousands of requests per second but not have the overhead (network cost & monetary costs) and possible production interference by going directly against Cosmos.
Azure Cosmos DB Emulator Not Working - Azure Lessons
To fix this issue, you just need to follow the below information. Close the command prompt. Run the command prompt with “Run as administrator” mode and rerun the command lodctr /R.; If you are again facing the same issue, close the command prompt again and rerun with “Run as administrator” mode meaning repeat the same for 2 to 3 times.
What is Azure Cosmos DB?
According to Microsoft’s Azure Documentation, Cosmos DB is “Microsoft’s globally distributed, multi-model database.” It offers geo-replication of the data and virtually unlimited scale storage. It provides multiple APIs that support efficient access to the multiple data models such as tables, graph and columnar.
How to deploy Cosmos DB?
To begin developing and deploying Azure Cosmos DB applications, you need to create an account on Azure portal. Once you log in to your account, click on Create a resource, and then you will see Azure Cosmos DB under Databases.
What is throughput in Cosmos?
Next comes Throughput, which is where you request and pay for the performance level that you want this collection to deliver. This is expressed in the form of request units or RU/s. There are no actual costs involved when you are using the emulator, but while using Cosmos DB on Azure portal lower, values deliver lower throughput at a lower cost, and higher values deliver higher performance at higher cost. For some data you may require high throughput, this the reason you may want to create multiple collections in the same database.
What is Cassandra API?
Cassandra API: This API is based on Columnar data storage feature. The data is physically stored in column-oriented fashion. You will have to provide schema upfront to be able to store the data.
Can you use Cosmos DB with local emulator?
As you can see, by using the local emulator you can simulate and run the queries without incurring any costs. This includes support for creating and querying the documents and scaling collections as needed. To make your applications globally scalable, you will have to update the connection string from the local emulator to an Azure Cosmos DB connection string. Essentially, you can develop your whole application using the local emulator and when you are ready, just deploy it to Azure with a small configuration change.
Does Cosmos DB have unlimited storage?
Create a new collection as shown below. Both the database and collection have the same name Employees. The option, Unlimited, was chosen for storage so that Cosmos DB will automatically handle horizontal partitioning based on the partition key. 1000 RU/s for throughput is way more than needed, but since this example uses the local emulator, high values are fine. Finally, since Unlimited storage was selected, the Partition key must be provided. This example uses zip code as the partition key. The employee document will have a property called zipCode nested in the address property.
Is a collection the same as a table in a Cosmos database?
Be it a table, graph or collection, it means all the same to Cosmos DB. A number of databases can be run on a single Cosmos DB server. Like the tables in an RDBMS, you have collections in the Cosmos DB. A collection may store multiple documents; hence documents are analogous to records in RDBMS.
How to start cosmosdb emulator from command line?
You can also start the Azure Cosmos DB emulator from the command line.
What is Azure Cosmos DB?
Azure Cosmos DB local Emulator provides you with the opportunity to develop and test your application locally.
Can you use Cosmos DB for production?
Since Cosmos DB Linux Emulator is in preview, it is not suggested to use for production. Use Cosmos DB Windows Emulator for production purposes.
Starting the emulator
Normally you would use the Windows start menu to find your programs and start the application, however, for the emulator to support MongoDB APIs, you will need to pass the EnableMongoDbEndpoint argument.
Getting the connection string
The very first thing you’d see is the quick start which should look something like this:
Testing the application
You’re now ready to get your celebrities via the API. Simply open a browser and head over to http://localhost:5000/api/celebrities or just use the below command:
Summary
In this guide we saw how to use Azure Cosmos DB Emulator with MongoDb API to have a local MongoDb available for our local development and proof of concepts. Hope this has helped you save some time and also the trouble of installing yet another software on your system (of course if you already are using the emulator 😊).
