With 400k rows, plain Postgres answered analytics queries in milliseconds — no Kafka or ClickHouse required. The post identifies three hidden costs of premature infrastructure: unnecessary spend, cognitive load on engineers, and lost velocity from complexity that was never needed. It also acknowledges when reaching for heavy tools early is genuinely justified. ## Content "This is an OLAP problem, so we need ClickHouse." That sentence almost cost me two databases I didn't need. 400k users. Analytics dashboards. I sketched the whole stack in minutes — Kafka streaming events into ClickHouse, dashboards reading from it. Clean. Scalable. The kind of diagram that looks like a company that's going to make it. Then I did the math I should've done first: 400k rows is tens of megabytes. Postgres answers those queries in single-digit milliseconds. I wasn't solving a bottleneck. I was building for one I had imagined and never measured. And this is the trap I see early-stage teams fall into again and again: Analytics? ClickHouse. Search? Elasticsearch. Scale? Kubernetes. Events? Kafka. We pattern-match a problem type to a fancy tool — and adopt it before we've confirmed we even have the problem. It never feels like a mistake. It feels responsible. You're "building for scale." But every box on that diagram is a bill you haven't read: → money spent before there's a workload to justify it → cognitive load every engineer now carries forever → velocity you quietly lose to complexity that was never load-bearing The future you're building for is a hypothesis. Your current bottlenecks are data. Most teams provision for the hypothesis and ignore the data. I wrote up the full story — what I built instead with plain Postgres, the three hidden costs, and (importantly) when reaching for the heavy tool early actually IS the right call. If you've ever added infra "for when we scale" — this one's for you.
