Hello,
I am experimenting the Delta dataset in parquet file in the sink activity...
I have the upsert if working for the .parquet files by selecting the upsert if setting to true()
For example when the source is updated ,then the parquet sink is updated accordingly. But if a row is deleted in source it is still shown in sink parquet file even when check the Allow Delete .Any suggestions?
Thank you
