Hello Osama Tarek,
Welcome to the Microsoft Q&A forum.
Delta lake with CDC is only available with Deltalake version 2.0.0
Reference document: https://docs.delta.io/2.0.0/versioning.html#features-by-protocol-version
Deltalake 2.0 is only supported in Synapse Spark 3.3
https://video2.skills-academy.com/en-us/azure/synapse-analytics/spark/apache-spark-33-runtime
So we do not support delta sink with CDC enabled in dataflow now
In adf, data flows are mostly use synapse spark 3.1.
Please note: Data flows will move to Spark 3.3/Deleta 2.x , but I don't have an ETA for this feature request.
I can follow up with PG and update this thread if I hear anything back from them.
