Event-Driven Analytics: Architecting for Scale and Correctness

As data volumes grow, traditional analytics architectures struggle with correctness and auditability. Event sourcing with CQRS provides a proven pattern for building analytics systems that are not only scalable but also replay-able and self-healing, making it essential for product analytics, telemetry, and operational metrics. This architecture enables teams to evolve schemas without breaking existing pipelines and derive insights retroactively from immutable event logs.
