Azure Cosmos DB Emulator Microsoft® Corporation
winget install --id=Microsoft.Azure.CosmosEmulator -e The Azure Cosmos DB emulator provides a local environment that emulates the Azure Cosmos DB service designed for development purposes. Using the emulator, you can develop and test your application locally, without creating an Azure subscription or incurring any service costs. When you're satisfied with how your application is working with the emulator, you can transition to using an Azure Cosmos DB account with minimal friction.
Azure Cosmos DB Emulator is a local development tool designed to emulate the Azure Cosmos DB service for testing and application development without requiring an Azure subscription or incurring cloud costs. It provides a cost-effective environment to iterate on your application locally before transitioning to a production environment.
Key Features:
- Cost-Free Development: Test applications locally without Azure subscription costs.
- Local Emulation: Mimics Azure Cosmos DB functionality, enabling accurate testing of features and performance.
- API Support: Works with the API for NoSQL and MongoDB APIs, allowing developers to test against these services in a controlled environment.
- Consistency Levels: Supports Session and Strong consistency levels, helping developers understand how their applications behave under different conditions.
- Container Limits: Ideally supports up to 10 fixed-size containers at 400 RU/s or 5 unlimited-size containers, though more can be created with potential performance impacts.
Audience & Benefit: Ideal for developers and development teams working on applications that integrate with Azure Cosmos DB or its APIs. The emulator accelerates the development cycle by enabling local testing, reducing reliance on cloud resources during the early stages of application design and iteration.
This tool is essential for teams looking to reduce costs, accelerate feature development, and ensure their applications are robust before deploying to a production environment.
