Redis Streams vs Pub/Sub: Performance

This post compares the performance of Redis Streams and Redis Pub/Sub by running a benchmark on AWS. It highlights the primary differences, emphasizes the stateless nature of Pub/Sub, and contrasts it with the durability of Redis Streams. The benchmark tests measure latency, throughput, and CPU usage, revealing that Pub/Sub can handle over 1 million messages per second with lower resources, while Streams provide higher durability at the cost of increased CPU usage and reduced throughput.
