CosmosDB Global Distribution - Multi-region Writes

Syntax

var database = client.GetDatabase("<database name>");
var collection = database.GetCollection("<collection name>");

var document = new BsonDocument
{
    { "<key>", "<value>" }
};

collection.InsertOne(document);

Example

Suppose you have a web application that is being used across the globe. You have a database hosted in one region and you're experiencing a high volume of writes. You want to improve the write performance of the application. You can achieve this by setting up multi-region writes in CosmosDB.

Output

After the implementation of multi-region writes in CosmosDB, your application will be able to handle a higher volume of writes, ensuring faster response times for your users, even if they are located in different parts of the world.

Explanation

CosmosDB's global distribution allows you to replicate your database across multiple regions. By creating replicas of your database in multiple regions, you can ensure that your application is able to handle a higher volume of reads and writes. When a write operation is performed, it is first replicated to the primary region and then to the secondary regions asynchronously. This ensures that your data is available in multiple regions for faster access.

Use

Multi-region writes can be used in scenarios where write performance is a critical requirement, and the application is being used by users across the globe.

Important Points

• Multi-region writes require you to have a minimum of two regions for your database.
• You need to specify the write regions for your database during the configuration.

Summary

Multi-region writes in CosmosDB helps to improve the write performance of your application. It allows your data to be replicated across multiple regions, ensuring faster response times for your users across the globe. By setting up multi-region writes, you can ensure that your application is resilient to network outages and disasters.
