Introduction

Google Sheets plugins will allow users to import data from Google Sheets into their pipeline, so that they can transform and enrich with other data sources.

User Storie(s)

  • As a pipeline developer, I want to import data from Google Sheets, so that I can transform and enrich it using CDAP
  • As a pipeline developer, I want to move all sheets from a given Google drive directory to a destination
  • As a pipeline developer, I want to be able to pick certain sheets from a particular sheet to process using CDAP, so that I do not have to process all sheets all the time. I want to be able to specify the sheet using the sheet name or number.
  • As a pipeline developer, I want to treat the first row of a sheet as a header, so that CDAP can automatically treat it as schema
  • As a pipeline developer, I want to be able to specify a section at the top of my Sheet as a header, so that it is extracted as metadata, and not as actual data
  • As a pipeline developer, I want to be able to specify a section at the bottom of my sheet as a footer, so that it is extracted as metadata, and not as actual data
