Work Smarter, Not Harder: Discover Your OpenSearch Clusters Breaking...
summary
OpenSearch Benchmark adds Redline Testing, a feedback-driven load test that starts at zero clients and dynamically ramps clients up or down by monitoring per-request latency, errors, and optional CPU metrics stored in a separate OpenSearch datastore. A feedback actor flips client booleans to throttle load, reports the cluster’s maximum stable throughput in the test summary, supports distributed generators and has reached up to 10,000 clients on c5.4xlarge during experiments.
