What are some best practices for configuring Kafka?

When configuring Kafka, consider the following best practices: 1. Set appropriate replication factors for fault tolerance. 2. Optimize partitioning to balance load. 3. Use proper retention policies to manage disk space. 4. Monitor performance metrics regularly.

How do I choose the right number of partitions?

The right number of partitions depends on your throughput needs and consumer parallelism. A good rule of thumb is to start with a number of partitions equal to the number of consumers you plan to have.

What should I set the replication factor to?

A common practice is to set the replication factor to at least 3 for production environments to ensure high availability and fault tolerance.

Can you explain how to configure retention policies?

Retention policies can be configured using the retention.ms and retention.bytes settings. retention.ms defines how long messages are retained, while retention.bytes limits the total size of the log.

What tools can I use to monitor Kafka performance?

You can use tools like Kafka Manager, Confluent Control Center, or open-source solutions like Prometheus and Grafana for monitoring Kafka performance.
