Subject [jira] [Updated] (AIRFLOW-2361) Allow GoogleCloudStorageToGoogleCloudStorageOperator to store list of copied files to XCom
Date Tue, 24 Apr 2018 21:02:00 GMT

     [ https://issues.apache.org/jira/browse/AIRFLOW-2361?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Berislav Lopac updated AIRFLOW-2361:
------------------------------------
    Description: 
When {{GoogleCloudStorageToGoogleCloudStorageOperator}} is used with a wildcard, it can copy
more than one file. It would be useful if there would exist a mechanism to store the list
of copied files as XCom so it can be used by other tasks downstream.

Proposed solution: Add a {{xcom_push}} flag argument to the constructor; if {{True}}, the
\{{execute }}method returns a report on copied files. The report is a dict of following structure:
{code:java}
[
    ["original/file/path.ext", "target/prefix/original/file/path.ext"],
    ...
}{code}
