Building Reliable Distributed Systems
summary
Shows how a manual saga of retries, compensation and state checks (Vercel function + MongoDB) becomes a compact workflow using Temporal workflows and the TypeScript SDK: start a workflow with a request ID, run activities run with retries and timeouts, persist every step in the cluster (Cassandra/Postgres/MySQL), and resume after crashes. Demos include an order flow that drops dozens of boilerplate retries into a few functions, use of timers, signals and queries, and claims like fewer lines of code and real users cutting weekly incidents to zero.
