Important notes
delimiter
parameter and wildcards in source objects is essential. These features are not native to the GCS API; they were implemented as a workaround that now heavily misuses thedelimiter
parameter. This implementation likely stems from the fact that the new parameter,match_glob
, did not exist when these features were initially implemented. By utilizing this parameter instead ofdelimiter
- the original issue resolves.match_glob
param is not supported by the official GCS Python API today. To deal with it, I copied and patched list_blob() directly from their source code to the hook. I'm unsure if it's OK to do regarding licensing and maintainability from our side. If it's fine, let me know if I need to add any additional licensing comments - otherwise, we'll have to wait until the official release (according to GCP's comment on my issue - it should be around Q3).GCSToGCSOperator
,GCSToSFTPOperator
,GCSToGoogleDriveOperator
), there is an internal logic that deals with wildcards in the store object(s) and calls thelist()
method with thedelimiter
param. To avoid any chances of breaking existing behavior, I intentionally avoided using thematch_glob
param there. I added commentary that instructs what should be changed when finalizing the deprecation.^ Add meaningful description above
