HEP Data Format Activity
        There is literally a flurry for some time
          Focus on columnar formats (storage or conversion)
            Dianna-HEP 
                 Parquet, Awkward Array, Femtocode, OAMap, etc
            iris-HEP
                 iDDS, Service-X, DOMA R&D
            ROOT Project
                 RDataFrame
            Others
                 COFFEA

       HEP Public Cloud Activity
        Many projects leverage public clouds
         HEPCloud (AWS)
         HTCondor (AWS)
         ICCEP GCPM Project (GCP)
         Atlas Data Ocean Project (GCP)
         Many other independent projects

       The Synthesis
        Why not combine all these ideas
         Analysis using a public cloud
            E.G. Google Cloud Platform (GCP)
         With a cloud storage friendly data format
            E.G. Parquet (https://parquet.apache.org/)
         Suitable for efficient memory representation
            E.G. PANDAS (https://pandas.pydata.org/)
         That Python oriented physicists find useful
        We should learn quite a lot

        How We Got Here
        August 2019
             Informal discussion started (Andrew Hanushevsky & Ross Thomson)
        September 2019
             Project conceptualized
        October 2019
             Project formalized
             On-boarded 20% Google engineer (Guilhem Tesseyre) 
        November 2019 onwards
             Various approaches investigated and tried
        February 2020
             On-boarded physics analyst (Shawfeng Dong SLAC ACF)

        Project Goals I
        Demonstrate efficient use of GCP for 
        physics analysis
          We are only addressing analysis here
             Using Python as the language
          The demonstration has two aspects
             Workflow for needed data flow setup
                   This usually requires data conversion
             Workflow for running an analysis job
