# CDC Orchestrator PRO Redis Benchmark

Generated: 2026-06-28T11:00:13Z

The harness executes `CDC::Orchestrator::Pro::HybridRuntime` directly.
Mailbox depth is an estimate of shard work waiting beyond configured inner concurrency.

## Summary

- Stable runs: 54/54
- Highest throughput: 16950.52 events/s (streams, 7 Ractors, 50 fibers)
- Pub/Sub is ephemeral; Streams and pgoutput retain their distinct replay semantics.
