Design and Optimization of Distributed and Local Shared Variables for Strategy Engine Services
By introducing distributed and local shared variables that propagate user profiles via trace context and cache parallel requests, the iQIYI strategy engine cuts redundant DMP calls, reduces traffic up to 25%, lowers P99 latency by nearly 50%, and achieves a 90% cost saving compared to step‑function micro‑services.
