> The requirement is to create a snapshot from the Kafka topic but NOT do 
> continual reads after that point. For example you might be creating a backup 
> of the data to a file.
> In order to achieve that, a recommended solution by Joel Koshy and Jay Kreps 
> was to expose the high watermark, as maxEndOffset, from the FetchResponse 
> object through to each MessageAndMetadata object in order to be aware when 
> the consumer has reached the end of each partition.
> The submitted patch achieves this by adding the maxEndOffset to the 
> PartitionTopicInfo, which is updated when a new message arrives in the 
> ConsumerFetcherThread and then exposed in MessageAndMetadata.
