What are the best practices for ensuring fault tolerance in Kafka?

To ensure fault tolerance in Kafka, you should consider replication, partitioning, and proper configuration of producers and consumers.

How does replication work in Kafka?

Replication in Kafka involves creating copies of data across multiple brokers. This ensures that if one broker fails, the data is still available from another.

What is the recommended replication factor?

A common recommendation is to set the replication factor to at least 3 to ensure high availability and fault tolerance.

Can you explain how partitioning affects fault tolerance?

Partitioning allows Kafka to distribute data across multiple brokers, which not only improves performance but also enhances fault tolerance by isolating failures.

What configurations should I focus on for producers and consumers?

Focus on setting appropriate acknowledgment levels for producers and configuring consumer groups to handle message processing efficiently.
