How to set Kafka Heap Size?

Setting Kafka Heap size is simple, by default Kafka runs with 512MB as the heap size. For increasing the heap size, set the following environment variable and restart Kafka.

export KAFKA_HEAP_OPTS="-Xmx2G -Xms2G"

Kafka will check for KAFKA_HEAP_OPTS before it starts and if there is no value set for this variable, it assigns 512MB as the value, else it will pick up the configured value.
