Pike 2.0: Meituan's Bidirectional Message Delivery Service Architecture and Features

Meituan’s Pike 2.0 replaces the Shark‑dependent Pike 1.0 with a four‑layer, TunnelKit‑based bidirectional messaging service that offers shared or independent channels, heartbeat‑driven keep‑alive, aggregated high‑QPS delivery, ordering guarantees, extensive monitoring, and plans for IoT and QUIC enhancements, achieving over 5 billion daily messages with sub‑220 ms latency.
