Alipay Double 11 Technology Internals Deep-Dive Guide
← Series hub ← Prev • Next → Answer-first: Alipay’s Double 11 technology deep dive reveals high-performance internals: binary Bolt RPC protocol multiplexing over single TCP streams, RocketMQ 2PC transactional messaging for async decoupling, OceanBase LSM-tree compaction tuning, and multi-zone Paxos quorum consensus to achieve 544,000 TPS payment processing. Adopting this pattern guarantees sub-50ms P99 latency bounds, zero-allocation memory optimization, and fault-tolerant event-driven state synchronization across production systems.
