I think I understand the source of my confusion. Most transforms (e.g. query) have one or more inputs and one or more outputs.
Table comparison has the input (updates) and specifies a second input (the master table) in the properties of the transform.
For the output you have two options:
- create a new flow. This will then create records with OP codes that show only the changes needed. This might then be consumed in a later CDC transform
- link directly to the master table. In this case the output the changes are applied directly to the master.
I was thinking of this first type and not understanding the second type was possible.
