how to wait next log message on the partition queue

[Ganesh Nikam]

HI All,

I have basic question on kafka partition. Lets say I have one topic with 
partition 0. There is one producer which is producing log messages for 
this topic and there is one consumer also which is consuming messages on 
this topic. Assuming consumer is faster, after some time it reaches to 
the last message on the partition. Now the questions are:
    1. If the consumer tries to fetch next message, then what value 
will be return by Kafka server to consumer for offset ?

    2. If I want my consumer to wait till producer sends next log 
message then how can I achieve this ? How can I make my consumer to wait 
for next message ?
