Hi @Volker,

How are you doing today?

As per my understanding, Just try using the mergeSchema option in your streaming read operation to ensure the stream picks up schema changes from the Bronze table automatically. This will help propagate the new schema changes, like column renaming or additions, to the Silver table. Additionally, make sure that the schema evolution is enabled for both the Bronze and Silver tables to accommodate these changes without restarting the stream. If you're dealing with column renames, you may need to implement manual handling for those to ensure the downstream transformations are consistent. Lastly, minimize downtime by using checkpointing, which ensures the stream continues where it left off after applying schema changes.

Give a try and let me know.

Regards,
