Real Time Logistics Infrastructure Design Questions

Designing infrastructure and architectures to support low latency, high throughput, and geographically distributed logistics systems. Core areas include real time order and location tracking, publish subscribe and event streaming patterns, connection models such as web sockets and long polling, partitioning and data locality for geo distributed workloads, consistency and eventual consistency trade offs, backpressure and rate limiting, handling intermittent connectivity and offline reconciliation, scaling and sharding strategies for time series location data, and operational concerns including observability, testing and capacity planning. Candidates should be able to reason about trade offs specific to delivery platforms and propose resilient designs for real time requirements.
