## AI overview

A tutorial demonstrates a real-time anomaly-detection architecture for financial transactions using CockroachDB, Kafka, Kubernetes, and change-data-capture pipelines. It walks through simulating production traffic, observing latency under load, scaling services, and provisioning the required infrastructure.

## Source excerpt

When it comes to real-time applications, resilience isn't a nice-to-have, it's a necessity. In this post, we'll walk through a live demo designed to stress-test CockroachDB's ability to detect anomalies in a stream of financial transactions. Along the way, we'll simulate production traffic, observe latency under load, and scale our detection pipeline on the fly.
