Design a minimal replica set with MongoDB Change Streams, handle resume tokens, and verify real‑time updates without polling.
Guidance on requirements, minimal design, trust boundaries, operational checks, failure modes, and design‑change triggers for MongoDB change streams.
A decision guide for reacting to MongoDB document changes. Compare change streams, indexed polling, and tailable cursors by topology, latency, and resumability, then implement a resumable watcher with a reconciliation fallback.
Learn how MongoDB Change Streams let you stream data changes in real time, with a Node.js example, trade‑offs, and concrete steps to set up a resilient consumer.
MongoDB Change Streams let you react to data changes in real time without polling, but they require a replica set and careful oplog management.
Change Streams turn MongoDB's oplog into an ordered, resumable event feed. Here's what they buy you over polling or dual writes, a working filtered consumer example, and where they fall short.
