> I am pushing data to kafka topic after every 1 second in python. And written 
> consumer to fetch data from topic with consumer timeout as 500 ms and 
> enable_auto_commit as false.
> Following are the scripts:
> 1) prod.py
> from kafka import KafkaClient,SimpleConsumer
> from kafka.producer import SimpleProducer
> import random, time
> kafka =  KafkaClient("localhost:9092")
> producer = SimpleProducer(kafka)
> i=0
> while(True):
>   l1 = ['Rahul','Narendra','NaMo','ManMohan','Sonia']
>   msg = str(i) + ',' + str(random.choice(l1))
>   print('putting data : '+msg) 
>   producer.send_messages("test", msg)
>   i = i + 1
>   time.sleep(1)
> 2) con.py
> from kafka import KafkaConsumer
> consumer = 
> KafkaConsumer('test',bootstrap_servers=['localhost:9092'],consumer_timeout_ms 
> = 500, enable_auto_commit = False)
> for message in consumer:
>     print ("%s:%d:%d: key=%s value=%s" % (message.topic, message.partition,
>                                           message.offset, message.key,
>                                           message.value))
> consumer.commit()
> My producer is continuously running. And I am  running consumer again when it 
> stops. For first time consumer works well and gets data for me on time. But 
> after first time its taking minimum 1 minute to maximum  5 minutes (or above 
> 5 min also) to get next data. It should give me data after 1 second or 
> maximum after 5 seconds. But its giving problem :( . 
> Also 1 thing which I observe is If I wait for starting consumer about 1 min 
> then data comes as expected.
> Please correct me if I am going wrong.
