Real-Time Analytics Stack with Kafka, Flink, and ClickHouse

Real-Time Analytics Stack with Kafka, Flink, and ClickHouse

April 30, 2025

In today’s digital businesses, real-time decisions require real-time data. At Essid Solutions, we design and implement low-latency analytics platforms using Apache Kafka, Apache Flink, and ClickHouse to deliver streaming insights at scale.


πŸ”§ Why Real-Time Analytics?

  • Detect anomalies or fraud in real-time
  • Optimize marketing campaigns instantly
  • Power recommendation engines and personalization
  • Monitor IoT or sensor data with live dashboards

Batch ETL isn’t fast enough when milliseconds matter.


βš–οΈ Core Components of a Real-Time Stack

  1. Data Ingestion – Apache Kafka, MQTT, WebSockets
  2. Stream Processing – Apache Flink or Kafka Streams for windowing, joins, enrichment
  3. Analytics Database – ClickHouse for ultra-fast OLAP queries
  4. Visualization – Grafana, Redash, Superset
  5. Monitoring & Alerting – Prometheus, Alertmanager

πŸ’Ό Use Case: Fintech Fraud Detection System

A fintech company wanted to detect suspicious transactions in real-time. We:

  • Ingested data via Kafka from APIs and mobile apps
  • Built Flink jobs for rule-based fraud scoring
  • Stored results in ClickHouse with sub-second queries
  • Visualized alerts in Grafana

Result: Reduced fraud resolution time from hours to seconds.
