Fault tolerance

Fault tolerance is critical for real-time data processing applications, as data loss can have severe consequences. Apache Kafka provides fault tolerance through replication and partitioning mechanisms, ensuring that data is not lost even if individual nodes fail.

  • Replication: Kafka replicates data across multiple nodes. If one node fails, the data can be recovered from the other nodes in the cluster. This ensures that data is always available, even if individual nodes fail.

  • Partitioning: Kafka partitions data across multiple nodes. This distributes the load and ensures that no single node becomes overloaded. If one node fails, the other nodes can continue to process data without interruption.
