Introduction
Google drive plugins will help users move entire files from source to destination. Along the way, users can potentially run transformations on unstructured data such as images, audio and video as well.
User Storie(s)
- As a pipeline developer, I want to move all files from a Google drive directory to a different destination
- As a pipeline developer, I want to move all files from a Google drive directory that satisfy a filter to a different destination
- As a pipeline developer, I want to pull all images from a Google drive directory, so that I can process them using image recognition APIs
- As a pipeline developer, I want to pull all audio and video files from a Google drive directory, so that I can process them to extract metadata and/or generate transcripts, or apply other enrichments.
- As a pipeline developer, I want to move all files from an FTP source into Google drive.

Properties
Modification date range
Filters files by last modified date. Available values:
- None - files will not be filtered.
- Last 7 days - from current time 7 days ago until current date and time, for example: from "2019-09-12T19:52:13.456" to "2019-09-19T19:52:13.456".
- Last 30 days - from current time 30 days ago moment until current date and time, for example: from "2019-08-20T19:52:13.456" to "2019-09-19T19:52:13.456".
- Previous quarter - from start of previous quarter until end of previous quarter, for example: from "2019-04-01T00:00:00.000" to "2019-06-30T23:59:59.999".
- Current quarter - from start of current quarter until current date and time, for example: from "2019-07-01T00:00:00.000" to "2019-09-19T19:52:13.456".
- Last year - from start of previous year until end of previous year, for example: from "2018-01-01T00:00:00.000" to "2018-12-31T23:59:59.999".
- Current year - from start of current year until current date and time for example: from "2019-01-01T00:00:00.000" to "2019-09-19T19:52:13.456".
- Custom - user should enter start and end dates by himself.
This filter is not interconnected with Filter property, so user is able to populate Modification date range with value what conflicts with Filter.
File properties
User can select some files' metadata provided by Google Drive API. Not all properties are available for now. Descriptions were obtained from Files overview.

|---|---|---|
| id | string | The ID of the file. |

File types to pull
All files in Google Drive can be divided by format between two types: Google formats and all other (binary). Google formats are hidden and can not be exported directly, instead of this they should be exported into any binary format firstly and only if this option is available for specified format. Binary files can be downloaded directly. User can specify which formats he wants download/export:
- Binary - will be downloaded directly (text/plain, image/bmp, video/mp4 etc.)
- Google Documents - will be exported to format specified in Google Documents export format property before.
- Google Spreadsheets - will be exported to format specified in Google Spreadsheets export format property before.
- Google Drawings - will be exported to format specified in Google Drawings export format property before.
- Google Presentations - will be exported to format specified in Google Presentations export format property before.
