Lets walk through the process to get this done. Its only when you start creating many similar hardcoded resources that things get tedious and time-consuming. However, as stated above, to take this to the next level you would store all the file and linked service properties we hardcoded above in a lookup file and loop through them at runtime. Basically I have two table source and target. Just to have the example functional, use the exact same configuration, except change the FileSystem or Directory value to effectively copy the file to another location. The Lookup Activity will fetch all the configuration values from the table and pass them along to the next activities, as seen in the below output. Why is 51.8 inclination standard for Soyuz? stageInsert: true) ~> sink2. Often users want to connect to multiple data stores of the same type. Inside ADF, I have a, Activity that fetches the last processed key from the target table. Thus, you will need to be conscious of this when sending file names to the dataset at runtime.
