title: Is there concurrent requests limit for file upload/download using DBRestClient (iOS SDK)?
body: <p>Is there concurrent requests limit for DBRestClient (iOS SDK)? On slower networks when multiple requests for file upload/download issued many of requests fail with error 1001. Any limit recommendations?</p>
  
  <p>While it's possible to build workaround by sequentially uploading/downloading file one by one, this seems overkill especially when multiple requests works fine when network is fast enough.</p>
