Performance Optimization of Multi‑Modal Transfer Route Stitching in Ctrip Backend
This article analyzes the challenges of stitching multi‑modal transport routes in Ctrip's backend, identifies performance bottlenecks through monitoring, profiling and benchmarking, and presents a series of optimizations—including code refactoring, indexing, multi‑way merge, multi‑level caching, preprocessing, multithreading, lazy computation, and JVM tuning—that collectively reduce latency and resource consumption.
