Azure Cosmos DB Cassandra API Overview

Azure Cosmos DB is a globally distributed, multi-model database service. The Cassandra API in Azure Cosmos DB provides a rich Cassandra-compatible data model and familiar query language. This allows you to leverage your existing Apache Cassandra applications and expertise with the benefits of a fully managed, globally distributed database service.

Key Benefits of Using Cassandra API with Azure Cosmos DB

• Global Distribution: Seamlessly replicate your data across any number of Azure regions with tunable consistency.
• Elastic Scalability: Scale throughput and storage independently and elastically, without downtime.
• Low Latency: Achieve single-digit millisecond latency for both reads and writes globally.
• High Availability: Benefit from 99.999% availability for globally distributed applications.
• Multi-Model Capabilities: While focusing on Cassandra API, Azure Cosmos DB also supports other APIs like SQL (Core), MongoDB, Gremlin, and Table.
• Schema Flexibility: Dynamically adjust your data schema without the complexities of traditional database migrations.
• Managed Service: Offload database administration tasks like patching, clustering, and scaling to Azure.

When to Use Azure Cosmos DB Cassandra API

The Cassandra API for Azure Cosmos DB is an excellent choice for:

• Migrating existing Apache Cassandra applications to a fully managed, cloud-native platform.
• Building new applications that require the familiar Cassandra data model and query language with global distribution and elastic scalability.
• Applications needing high availability and low latency across multiple geographic regions.
• Use cases such as IoT data ingestion, real-time analytics, gaming leaderboards, and time-series data.
