Copy data activity not overwriting
We have also noted some odd behaviour with the Copy Data acivity.
It appears to have started from the 15th August for us. Where data is not being overwritten even though the overwrite option is set.
We managed to solve this issue with help from Mictosoft Support. The overwrite option when selected in a copy data activity has been updated to carry out OverwriteSchema.
"OverwriteSchema" action does not delete any data. Instead, it creates a new version of the Delta table with the updated schema, allowing users to leverage the time travel feature to view all previous versions of the table.
To perform an Overwrite, where the current data is completely replaced with the newly copied data, select 'Add dynamic content' for the Table Action and enter 'Overwrite'.
