Azure Cosmos DB (Cassandra API) — Technology Profile & Architecture

Core Information

#core_information

Name, description, vendor website, logo, technology type and tags.

Overview & Role

Azure Cosmos DB's Cassandra API is a fully managed, globally distributed, multi-model database service that provides wire-protocol compatibility with Apache Cassandra. It allows developers to use existing Cassandra drivers and tools to interact with Cosmos DB, leveraging its benefits like global distribution, elastic scalability, and high availability without managing infrastructure.

Performance Profile

#performance_profile

Typical read and write throughput, payload size and processing latency.

Read Performance Profile

Throughput: Hundreds of thousands to millions of operations/sec (RU/s), scales linearly with provisioned RUs

Payload Size: Typically 1KB - 4KB for point reads, up to 1MB for larger queries

Processing Latency: P99 latency <10 ms for point reads (single-digit milliseconds)

Write Performance Profile

Throughput: Hundreds of thousands to millions of operations/sec (RU/s), scales linearly with provisioned RUs

Payload Size: Typically 1KB - 4KB for common writes, up to 1MB per item

Processing Latency: P99 latency <10 ms for point writes (single-digit milliseconds)
