Learning Azure Cosmos DB

By: Shahid Shaikh

Overview of this book

<p>Microsoft has introduced a new globally distributed database, called Azure Cosmos DB. It is a superset of Microsoft's existing NoSQL Document DB service. Azure Cosmos DB enables you to scale throughput and storage elastically and independently across any number of Azure's geographic regions.</p> <p>This book is a must-have for anyone who wants to get introduced to the world of Cosmos DB. This book will focus on building globally-distributed applications without the hassle of complex, multiple datacenter configurations. This book will shed light on how Cosmos DB offers multimodal NoSQL database capabilities in the cloud at a scale that is one product with different database engines, such as key-value, document, graph, and wide column store. We will cover detailed practical examples on how to create a CRUD application using Cosmos DB with a frontend framework of your choice. This book will empower developers to choose their favorite database engines to perform integration, along with other systems that utilize the most popular languages, such as Node.js. This book will take you through the tips and trick, of Cosmos DB deployment, management, and the security offered by Azure Cosmos DB in order to detect, prevent, and respond to database breaches.</p> <p>By the end of this book, you will not only be aware of the best capabilities of relational and non-relational databases, but you will also be able to build scalable, globally distributed,<br />and highly responsive applications.</p>

Performing CRUD operations in Cassandra.


Cassandra API provides us the ability to store NoSQL data efficiently and easily in Cassandra. You need to create a new Cassandra database inside Cosmos DB to perform the CRUD operation.

  1. Log in to your Azure portal and click on the Azure Cosmos DB option on the left side of the options bar.
  2. Click on the + button and give your new database a proper ID, then choose the Cassandra option from the API dropdown.
  3. You can create a new resource or use the existing one. Select the location where most writing will happen and click on the Create button. You can refer to the screenshot for reference:

  1. Now, click on Data explorer |  New Table button and create a new table to store the data. Refer the screenshot below for the reference.
  1. Now, we can insert data using the standard SQL commands as shown below.
INSERT INTO uprofile.user
(first_name, last_name)
VALUES ('Shahid', 'Shaikh');
  1. You can read data from the Cassandra table using the SELECT query.
SELECT * from uprofile...
