Load testing with F1
summary
Open source F1 is a load tester written in Go that lets tests use goroutines and channels to stitch HTTP 202 responses to SQS messages for true asynchronous verification. It implements multiple injection modes including constant mode (fixed rate) and a virtual user pool; demoed at 1 request/sec for correctness and a pool producing ~1,000 req/s. The tool runs in CI, injects hundreds of thousands/sec in preprod, and uncovers scalability and bottleneck issues before production.
