Original: Real-Time Analytics: When You Need It and When You Don't

Short summary

Most teams requesting 'real-time analytics' actually need fast-enough data, not sub-second streaming. Pre-aggregation caching through a semantic layer covers 90% of use cases at a fraction of the cost of Kafka/Flink architectures. True real-time is only justified for fraud detection, live monitoring, trading, and live events. Configure per-metric refresh intervals to match actual freshness requirements.

  • •90% of 'real-time' requests are satisfied by pre-aggregation caching refreshing every 15 minutes
  • •True real-time streaming is only needed for fraud detection, live monitoring, trading, and live events
  • •Per-metric refresh configuration lets you balance freshness and cost across different use cases
