- 1. Introduction to Apache Kafka & Event Streaming
- 2. What is Apache Kafka? Apache Kafka is an open-source distributed event streaming platform. Originally developed by LinkedIn, now part of Apache Software Foundation. Designed for real-time data processing, messaging, and event-driven architectures. Handles high-throughput, low-latency, and fault-tolerant data streaming.
- 3. Why Use Apache Kafka? ✅ Scalability – Handles millions of events per second. ✅ Durability – Stores events for long-term retrieval. ✅ Fault Tolerance – Replicates data across multiple nodes. ✅ High Performance – Processes real-time and batch data efficiently. ✅ Decouples Services – Enables microservices and event-driven architecture.
- 4. Kafka Architecture Overview Producers – Publish events/messages to Kafka topics. Topics – Logical categories where events are stored. Partitions – Distributes data across multiple brokers for scalability. Brokers – Kafka servers that manage message storage and retrieval. Consumers – Subscribe to topics and process messages. ZooKeeper – Manages Kafka metadata and broker coordination.
- 5. Key Components of Apache Kafka 🔹 Producers – Send data to Kafka topics. 🔹 Topics & Partitions – Store and organize messages. 🔹 Brokers – Handle storage, replication, and retrieval. 🔹 Consumers – Subscribe and process events. 🔹 ZooKeeper – Coordinates brokers and manages leader elections.
- 6. Event Streaming with Kafka Kafka enables real-time event streaming across applications. Event Producers generate data continuously (e.g., IoT sensors, logs, transactions). Kafka Streams API allows real-time processing of streaming data. Event Consumers process and act upon streamed data (e.g., analytics, monitoring).
- 7. Use Cases of Kafka ✅ Real-Time Analytics – Process and analyze live data. ✅ Log & Metrics Aggregation – Centralize logs for monitoring. ✅ Fraud Detection – Identify suspicious transactions in real-time. ✅ IoT & Sensor Data Processing – Stream data from connected devices. ✅ Messaging & Microservices – Enables scalable, decoupled architectures.
- 8. Feature Throughput Storage Scalability Processing Model Apache Kafka High (millions of events/sec) Retains messages for days/weeks Horizontally scalable Pub-Sub & Event Streaming Traditional Messaging (e.g., RabbitMQ) Moderate Messages are deleted after consumption Limited scalability Queue-based Kafka vs. Traditional Messaging Systems
- 9. Conclusion Apache Kafka is a powerful event streaming platform for handling real- time data. Provides high throughput, fault tolerance, and scalability. Ideal for big data pipelines, microservices, and analytics.
