Kafka vs SQS
Compare multiple streaming and messaging technologies
What is the difference between Kafka and SQS?
Kafka is a distributed streaming platform optimized for persistent, ordered event streams and complex real-time processing, allowing data replay. Amazon SQS is a fully managed message queuing service primarily used for decoupling application components with simple, reliable, and scalable message delivery, not designed for streaming data replay or ordered streams (unless using FIFO queues).
Feature |  Kafka |  SQS |
|---|---|---|
Event Streaming PlatformIs this system fundamentally designed for handling continuous, high-volume streams of events, often for real-time analytics or data pipelines? | ||
Traditional Message QueueIs this system primarily optimized for point-to-point communication, task queues, and ensuring reliable delivery of individual messages? | ||
Message Replay SupportCan consumers re-read or 'rewind' to process messages from any point in history, even if they've been consumed before? | ||
Strict Message OrderingDoes the system guarantee that messages are delivered and processed in the exact order they were sent within a logical partition or queue? | ||
Open SourceIs the core project an open-source technology with its source code publicly available? | ||
Easy to Setup & MaintainHow straightforward is the initial setup, configuration, and ongoing operational management of this system? | ||
Stream Processing EngineIs this a dedicated engine for processing and transforming data streams in real-time? |
