As buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, Amazon S3 uses pagination to split them into multiple responses. Following is a pseudo-code procedure that demonstrates how to iteratively fetch an exhaustive list of results, given a prefix, marker and delimiter.
Example
function exhaustiveList(bucket, prefix, marker, delimiter) :
do {
result = AmazonS3.list(bucket, prefix, marker, delimiter);
// ... work with incremental list results ...
marker = max(result.Contents.Keys, result.CommonPrefixes.Prefixes)
// or more conveniently, when delimiter != null
// marker = result.NextMarker;
}
while (result.IsTruncated);
