Copy data activity not overwriting
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'.
Thanks for the update. Do you know if there is any documentation on the change? I've been looking here https://learn.microsoft.com/en-us/fabric/data-factory/copy-data-activity but couldn't find anything.
Hi,
Same issue this side, which is clearly that overwrite now appends instead of its intended functionality. Not a user-side issue.
Must say, working with Fabric has been challenging at times...
