title: Store pandas df in s3 and be able to retrieve single column
body: <p>I try to save pandas df-like object in AWS S3 and retrieve it in Jupyter Notebook. In my solution I have to be able to retrieve single column from it, so .csv is not good solution. I thought about using .h5 files, saved dataframe and stored it as that kind of file in my S3, but when i try to call:</p>
  <pre><code>pd.read_hdf('https://mytests3h5storage-123.s3.amazonaws.com/iris.h5')
  </code></pre>
  <p>i got:</p>
  <p><em>FileNotFoundError: File <a href="https://mytests3h5storage-123.s3.amazonaws.com/iris.h5" rel="nofollow noreferrer">https://mytests3h5storage-123.s3.amazonaws.com/iris.h5</a> does not exist</em></p>
  <p>and I am 100% sure that file exist.</p>
  <p>I find info that other people have same problems, so may be it is not implemented. Is there any good way to solve it? I need to retrieve single column (or few of them) in Lambda and use it there.</p>
