Reviewer scorecard
“Atlas is excellent — search, vector, triggers, and serverless functions. The aggregation pipeline is powerful once you learn it.”
“Essential infrastructure for any app that needs caching or pub/sub. Upstash makes it serverless and affordable.”
“Document databases create more problems than they solve for most apps. Start with Postgres, add MongoDB only if you truly need it.”
“The license change burned some goodwill but Redis is still the best at what it does. Valkey is the hedge.”
“Atlas Vector Search positions MongoDB well for AI applications. Their platform play is smart.”
“Redis modules (search, graph, time series) make it more than a cache. The platform expansion is working.”
