title: What should I do about this gsutil "parallel composite upload" warning?
body: <p>I am running a python script and using the <code>os</code> library to execute a <code>gsutil</code> command, which is typically executed in the command prompt on Windows. I have some file on my local computer and I want to put it into a <code>Google Bucket</code> so I do:</p>
  
  <p>import os</p>
  
  <pre><code>command = 'gsutil -m cp myfile.csv  gs://my/bucket/myfile.csv'
  os.system(command)
  </code></pre>
  
  <p>I get a message like: </p>
  
  <blockquote>
    <p>==> NOTE: You are uploading one or more large file(s), which would run significantly faster if you enable parallel composite uploads. This
    feature can be enabled by editing the
    "parallel_composite_upload_threshold" value in your .boto
    configuration file. However, note that if you do this large files will
    be uploaded as 'composite objects
    <a href="https://cloud.google.com/storage/docs/composite-objects" rel="noreferrer">https://cloud.google.com/storage/docs/composite-objects</a>'_, which
    means that any user who downloads such objects will need to have a
    compiled crcmod installed (see "gsutil help crcmod"). This is because
    without a compiled crcmod, computing checksums on composite objects is
    so slow that gsutil disables downloads of composite objects.</p>
  </blockquote>
  
  <p>I want to get rid of this message either by hiding it if it's irrelevant od actually doing what it suggests, but I can't find the .boto file. What should I do?</p>
