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.

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 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.

File body field	String	Name of the schema field (should be BYTES type) which will be used as body of file. The minimal input schema should contain only this field.	No

Design / Implementation Tips

Tip #2

Design

Approach(s)

Source

Google Drive Source plugin reads files from specified Google Drive folder via Drive API.

Output schema if fully defined by plugin settings provided by user. Two fields are mandatory: body and offset, all other depends on file's fields selected in File properties property.

Body format is defined by Body output format property and may be Bytes and String formats. Offset field provides number of byte in the original file body starts from.

Plugin is able to limit maximal body size per partition with Maximum partition size set. For default value 0 plugin processes entire files without partitioning and offset field has always 0 value.

Sink

Google Drive Sink plugin writes received data as files to specified Google Drive folder via Drive API.

Sink writes single separate file per received partition. The only required input field is the file's body. The name of the schema's field with file body can be specified with File name field property. BYTES format is only supported for body input field. There are also similar properties for name and mime type of file. Both requires STRING format. In case name field is not specified sink will generate random 16-symbol names. In case mime type field is not set Google Drive will try define it automatically.

Sink plugin doesn't support partitioned files writing.
