The Data Factory also includes a pipeline which has pipeline parameters for schema name, table name, and column expression to be used in dynamic content expressions. The technical storage or access that is used exclusively for anonymous statistical purposes. The technical storage or access is necessary for the legitimate purpose of storing preferences that are not requested by the subscriber or user. ). Simplify and accelerate development and testing (dev/test) across any platform. To process data dynamically, we need to use a Lookup activity component to fetch the Configuration Table contents. Basically I have two table source and target. Therefore, this is an excellent candidate to split into two tables. It may be a good idea to split the source and configuration tables into two tables since it will be harder to maintain a single configuration table. The path for the parameterized blob dataset is set by using values of these parameters. Check your spam filter). I went through that so you wont have to! Lets change the rest of the pipeline as well!
