[jira] [Created] (PIO-193) Use async requests to storage whenever possible

Chris Wewerka created PIO-193:
---------------------------------

             Summary: Use async requests to storage whenever possible
                 Key: PIO-193
                 URL: https://issues.apache.org/jira/browse/PIO-193
             Project: PredictionIO
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.13.0
            Reporter: Chris Wewerka
             Fix For: 0.14.0


The storage access in Prediction IO uses blocking drivers and uses the standard scala ExecutionContext which is a bounded ForkJoin ThreadPool. This leads to bad usage of machines resources.
