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

You can pass java parameters from command line . E.g.

java -server -Xms3072m -Xmx3072m -XX:NewSize=256m -XX:MaxNewSize=256m  -classpath  foo.class

For a `production server config you can create a properties file or set them in Code by creating

 Properties props = new Properties();
 props.put("serializer.class", "kafka.serializer.StringEncoder");

And then supply them to producerConfig

ProducerConfig config = new ProducerConfig(props);
