what does --max-messages argument mean ?

[mingleizhang]

Hello all, 


     I wrote a bash script to get some message from kafka. And I set the 
argument --max-messages like --max-messages 1000. What I have got is just ONE 
message from the log! And the file size seems 1000 bytes instead. I want to 
know what is happening ? I expect that I will get 1000 messages, but actually. 
It doesnt, who can improve my mind ?


Thanks
Rice.
