Hi Stefan-Koch,

We reached out to our account rep and was instructed to create an Azure support ticket since we do not yet have a paid support plan.  We are hoping to negotiate for paid support.  However, I do not believe the documentation surrounding the Apply Changes feature is not robust enough to describe the constraints and dependencies.  The whole point of the create_streaming_table is to guarantee that the validation stage won't fail.  My approach is to build configuration driven DLT pipelines given our limited staff and time rather than hand-crafting hundreds of DLT pipeline notebooks.  In order to get that to work, I need to inject the schema and expectations from an external definition.  The create_streaming_function's parameter-list does support schema and expectations according to the docs, but the feature doesn't seem to work at all. The pipeline succeeds, but the Data Quality tab indicates there are no data quality definitions defined.  

When I learn something I will definitely post the answer here.
