>                 URL: https://issues.apache.org/jira/browse/STORM-1471
>             Project: Apache Storm
>          Issue Type: Bug
>          Components: storm-kafka
>            Reporter: Garrick Dasbach
>
> We currently have an issue in our storm cluster where our Kafka brokers are 
> under heavy load due to too many fetch requests from storm.  We've narrowed 
> the problem to the way Fetch Requests are build in KafkaUtils.  When using 
> the FetchRequestBuilder, storm provides overrides for all the properties 
> except minBytes.  The default for that field is 0 (even though the Kafka 
> default for the high-level consumer is 1).  When paired with a maxWait > 0, 
> this creates a situation where the broker can immediately return a response 
> without waiting (due to minBytes 0).  This puts a heavy load on the brokers 
> and defeats the purpose of any long polling.
> By making this a SpoutConfig option, it will allow the user to set that as 
> appropriate for their situation.
