Key Features of Apache Kafka

‍

1. Distributed Architecture
   • Description: Kafka runs on multiple servers that share and copy data.
   • Impact: Makes sure Kafka is always available and can handle large amounts of data reliably.
2. Scalability
   • Description: Kafka can grow by adding more servers to the system.
   • Impact: Handles increasing amounts of data and more users without slowing down.
3. Durability and Reliability
   • Description: Kafka copies data across different servers to keep it safe.
   • Impact: Protects against data loss and keeps data available even if some servers fail.
4. Real-Time Processing
   • Description: Allows data to be received and processed immediately using tools like Kafka Streams, Apache Flink, and Apache Spark.
   • Impact: Provides instant insights and actions based on new data as it comes in.
5. Flexible Data Integration
   • Description: Connects easily with various data sources and destinations using many available connectors in Kafka Connect.
   • Impact: Makes it simple to move data between different systems and applications.
