Postgres with QUIC: Why Stream Multiplexing Beats Traditional TCP Connection Pooling
Summary
The Lupyd article examines running PostgreSQL over QUIC to address client-side TCP connection bottlenecks. It presents benchmark results showing dramatically higher throughput (up to ~9,718 QPS) and lower latency under load with QUIC and stream multiplexing, compared to traditional TCP pooling, while also noting limitations such as multi-statement transactions still pinning backend connections. The piece includes implementation details using tokio-postgres with s2n-quic and notes open-source repositories for further exploration.
