> The current AWS S3Consumer class has a problem if user supply the parameter deleteAfterRead=false.
 The S3Consumer will always consume the same files over and over again with the size of getMaxMessagesPerPoll().

> After some code chasing, i think, the root cause is because the ListObjectsRequest does
not has the previous marker value. Hence, i wonder if we could do something like below:
> {quote}
> {color:blue}private string marker; // new line to define the marker string {color}
> ..
> ..
> ..
> ListObjectsRequest listObjectsRequest = new ListObjectsRequest();
> listObjectsRequest.setBucketName(bucketName);
> listObjectsRequest.setPrefix(getConfiguration().getPrefix());
> listObjectsRequest.setMaxKeys(maxMessagesPerPoll);
> {color:blue}listObjectsRequest.setMarker(marker); // new line to set the marker  {color}
    
> ObjectListing listObjects = getAmazonS3Client().listObjects(listObjectsRequest);
> {color:blue}marker = listObjects.getMarker(); // where marker is track          
> {color}{quote}
