I'm following the ConsumerGroup example, https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example
How can I specify the batch size of the messages that I want to consume? I see that if I use the SimpleConsumer, I can specify a size that I want to read. How can I do it here with the ConsumerGroup? I want to be able to consume let's say 1000 records, process them and so on...
