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

Looking at kafka-run-classh.sh - kafka uses the following variables:

• $KAFKA_HEAP_OPTS
• $KAFKA_JVM_PERFORMANCE_OPTS
• $KAFKA_GC_LOG_OPTS
• $KAFKA_JMX_OPTS
• $KAFKA_LOG4J_OPTS

You can run it via:

export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G" 
export KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12346 -Dcom.sun.management.jmxremote.rmi.port=12346 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false" 
bin/kafka-server-start.sh -daemon config/server.properties
