redis/pubsub-sub-bench repository overview

⁠pubsub-sub-bench

Benchmark tool for measuring Redis Pub/Sub subscriber throughput and latency at scale.

⁠Quick Start

docker pull redis/pubsub-sub-bench

# Start Redis
docker run -d --name redis redis:8.6

# Run subscriber benchmark
docker run --rm --link redis:redis redis/pubsub-sub-bench   --uri redis://redis:6379   --subscribers 100   --channels 10   --test-time 30

⁠Features

• High-concurrency: test with thousands of concurrent subscribers
• Channel patterns: benchmark SUBSCRIBE and PSUBSCRIBE
• Latency measurement: end-to-end message latency percentiles (p50, p99, p999)
• Cluster support: connect to Redis Cluster via --cluster
• JSON metrics output: structured results for CI/CD pipelines

⁠Use Cases

• Validate Pub/Sub throughput before and after Redis upgrades
• Capacity planning for high-subscriber workloads
• Regression testing for message fanout scenarios
