As of now we're removing type input mapping attribute in Redshift transformations.
All tables which were set to be created using CREATE VIEW from another schema will now be automatically created using CREATE TABLE and the data will be copied.
There are many reasons behind this update, the most important being a deadlock when deleting tables in Storage that had a view created in a transformation or in an orphaned sandbox.
You may experience slightly slower transformation times and heavier disk usage caused by physically copying data.
Should you experience any unexpected behaviour or a major slowdown, please let us know.
PS: No action required, we're glad you made it here safely.
