Redis streams: a different take on event-driven
A different take on event driven.
Redis Streams are a powerful data structure in Redis designed for handling real-time, high-throughput event data. They combine the simplicity of an append-only log with advanced features for event consumption and processing, making them ideal for use cases like event sourcing, sensor data collection, and notification systems.
What are Redis Streams ?
A Redis stream acts as an append-only log where each new entry is assigned a unique, time-based ID. Unlike traditional logs, Redis Streams support random access in O(1) time and enable complex consumption patterns, such as consumer groups for distributed processing. This makes them suitable for scenarios where you need to record, syndicate, and process events in real time.
Key characteristics:
Append-only: Once data is written, it cannot be modified.
Immutable entries: Each entry is a set of key-value pairs with a unique ID.
Real-time syndication: Multiple consumers can process events as they arrive.
Trimming and retention: Streams can be trimmed to prevent unbounded growth.
