(SM 2005) SAP - GCP communication

Communication to Google Cloud platform is established through Datavard Java connector using Google SDK.

Data transfer process is following a standard pattern of 2 phased approach:

1. Data is fetched from SAP with open cursor with defined package size

2. Data package is saved temporarily as a csv file

3. File is transferred into Google Storage using Java APIs (com.google.cloud.storage)

4. Files are ingested into Google BigQuery from Google Storage using Java APIs (com.google.cloud.bigquery)
