Welcome to the Azure Cosmos DB Design Pattern Samples repository! This collection showcases a variety of design patterns that can be employed to build robust and efficient applications using Azure Cosmos DB's NoSQL capabilities. Each pattern addresses specific scenarios and challenges, offering guidance and best practices for implementation.
Design patterns play a crucial role in building robust applications and modeling data effectively. They offer structured solutions to common challenges, providing numerous benefits that contribute to the success of your projects.
-
Efficiency and Best Practices: Design patterns encapsulate proven solutions, saving you time and effort by leveraging established best practices.
-
Scalability and Performance: Many patterns are optimized for scalability, ensuring your application can handle growth without compromising performance.
-
Consistency and Maintainability: Patterns promote consistent architecture, making codebases easier to understand, maintain, and extend.
-
Reliability and Resilience: Patterns address fault tolerance and error handling, resulting in applications that gracefully recover from failures.
-
Flexibility and Adaptability: Patterns facilitate changes, enabling your application to evolve and adapt to new requirements seamlessly.
-
Reusability and Accelerated Development: Patterns encourage reusable components, speeding up development and reducing the risk of bugs.
-
Effective Data Modeling: In NoSQL databases like Azure Cosmos DB, choosing the right pattern ensures efficient data modeling for enhanced performance.
-
Documentation and Communication: Patterns provide a shared vocabulary, aiding communication and collaboration among team members.
-
Adherence to Best Practices: Design patterns ensure applications adhere to security, data integrity, and maintainability best practices.
-
Reduced Learning Curve: Developers familiar with patterns quickly understand and contribute to projects, reducing onboarding time.
Explore the following design patterns to enhance your understanding of building applications with Azure Cosmos DB:
This pattern demonstrates how to use attribute arrays to efficiently store and query multiple attributes of an entity within a single document. Dive into the attribute-array
folder for a comprehensive guide on how to get started.
Learn how to leverage data binning to organize and group data points into predefined bins for easy analysis and retrieval. Discover the data-binning
folder for step-by-step instructions on implementation.
Implement a distributed counter to efficiently maintain and update counts across multiple documents. Find detailed instructions in the distributed-counter
folder to get started.
Explore the distributed-lock
pattern to learn how to implement distributed locks for managing concurrent access to resources in Azure Cosmos DB.
Discover how to manage document versioning effectively within Azure Cosmos DB. The document-versioning
folder provides guidance on handling document changes over time.
Uncover the power of event sourcing for building applications that maintain a history of changes as a sequence of events. Explore the event-sourcing
folder for in-depth instructions.
Learn how to create and manage materialized views to efficiently retrieve precomputed data from Azure Cosmos DB. Refer to the materialized-view
folder for implementation details.
Explore the preallocation
pattern to understand how to preallocate resources, such as document IDs, to optimize performance and resource utilization.
Dive into the schema-versioning
folder to learn how to manage changes to your data model over time with the schema versioning pattern.
Navigate to the individual folders of each design pattern for a dedicated README.md
file that provides step-by-step instructions on how to implement and work with the pattern in your applications.
You can try out these design patterns using a free Azure Cosmos DB account, making it easy to experiment with Azure Cosmos DB before making a commitment. No credit card is required to get started, and your account is free for 30 days. After the initial 30-day period, you can create a new sandbox account. Additionally, you have the option to extend the trial beyond 30 days for an additional 24 hours. If you decide to upgrade, you can do so at any time during the 30-day trial period.
Sign up for your free Azure Cosmos DB account at aka.ms/trycosmosdb.
This opportunity provides a risk-free environment to explore these design patterns and see how Azure Cosmos DB can enhance your application development and data modeling efforts. Whether you're an experienced developer or just getting started, the free trial allows you to discover the benefits firsthand.
Happy coding with Azure Cosmos DB and these powerful design patterns!
