Google Cloud Transfer Service Operators

Prerequisite Tasks

To use these operators, you must do a few things:

CloudDataTransferServiceCreateJobOperator

Create a transfer job.

The function accepts dates in two formats:

  • consistent with Google API

    { "year": 2019, "month": 2, "day": 11 }
    
  • as an datetime object

The function accepts time in two formats:

  • consistent with Google API

    { "hours": 12, "minutes": 30, "seconds": 0 }
    
  • as an time object

If you want to create a job transfer that copies data from AWS S3 then you must have a connection configured. Information about configuration for AWS is available: Amazon Web Services Connection The selected connection for AWS can be indicated by the parameter aws_conn_id.

For parameter definition, take a look at CloudDataTransferServiceCreateJobOperator.
