Azure Data Factory - Is there a way to pass in an expression via parameter to a Data Flow such that it could be used in a Derive activity?
The purpose would to leverage a Lookup activity to pull the expression from a config file or database so you could more easily customize the output without requiring a custom Data Flow for each of the desired custom outputs. We have a standard set of "flows" which output a canonical structure. However, we are intending to offer the ability to include a custom set of data for each source. Instead of maintaining "n" number of Data Flow instances per source, I would like to use the standard Data Flow and pass in the custom expression.
