Kafka configuration options

When you configure Kafka, you must consider several key properties.

Kafka heap size:

  • KAFKA_HEAP_OPTS - The Kafka-broker JVM is set to 1 Gb by default.

General settings in the file:

  • - Ensure that the value of this setting is greater than or equal to the number of disks that are dedicated for Kafka.
  • - Ensure that the value of this setting is adjusted based on the number of producers, consumers, and the replication factor.
