Postgres LISTEN/NOTIFY scales to 60K writes/sec with batching
DBOS re‑engineered Postgres LISTEN/NOTIFY by buffering NOTIFY calls and adding a safety‑net poll, cracking 60 000 writes per second on a single server with millisecond latency. The trick sidesteps the global exclusive lock that traditionally throttles NOTIFY, proving the mechanism can serve high‑throughput, low‑latency streaming or pub/sub workloads without sacrificing durability.
