title: Python: getting the first 100 most recent keys in amazon s3 bucket
body: <p>I tried using boto, but it has the <code>.list()</code> method, which takes way to long for my data set, and the <code>.get_all_keys()</code>, which gets it random. I want to get about 100-1000 of the most recent keys in my S3 bucket, which has millions of keys in it. What is the most efficient way of doing this.</p>
