How do I set the Java options for Kafka?

Question

I\'ve been experimenting with Kafka and saw from the documentation on the main site that you\'re able to set different options for the jvm like heap size and the garbage col

Answer 1

Another way to do this is by modifying information written in /bin/kafka-server-start.sh:

export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"

or in /bin/kafka-run-class.sh:

KAFKA_JVM_PERFORMANCE_OPTS="-server -XX:+UseCompressedOops -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSScavengeBeforeRemark -XX:+DisableExplicitGC -Djava.awt.headless=true"
