1.2 Why Kafka?

Learn what makes Kafka ideal for real-time data processing. Explore use cases including real-time analytics, event sourcing, and log aggregation, with examples from Uber, LinkedIn, and Netflix.

Why Kafka?

What is Apache Kafka?

  • Distributed streaming platform designed for high-throughput message processing
  • Excels at handling low-latency, fault-tolerant data streams
  • Go-to solution for processing large volumes of real-time data
  • Seamlessly manages real-time data feeds across distributed systems

Common Use Cases

Real-time Analytics

  • Process data as it flows in for immediate insights
  • Enable faster decision-making with live data
  • Essential for monitoring user interactions
  • Track financial transactions in real-time

Event Sourcing

  • Record every state change as an event
  • Reconstruct entire application state from event history
  • Critical for financial services requiring auditability
  • Provides complete traceability of system changes

Log Aggregation

  • Centralize logs from various services
  • Simplify monitoring and analysis
  • Common setup for microservices architectures
  • Each service generates logs collected by Kafka

Metrics Collection

  • Collect performance metrics across distributed systems
  • Process metrics in real-time
  • Provide unified view of system health
  • Monitor application performance centrally

Data Integration

  • Serves as backbone for connecting different data sources
  • Ensures data consistency across applications
  • Integrates heterogeneous systems seamlessly
  • Maintains data flow between various platforms

Real-World Examples

Uber

  • Processes millions of trip events per second
