Where is the Skipped dependency between ADF or Synapse pipeline activities useful for?
 |
| Skipped dependency |
Solution
The Skipped dependency will execute the next activity if the previous activity is not executed. For example because the activity before that previous activity failed.
You could for example use this to create a general event handler for the entire pipeline by connecting the end of each 'line' to a dummy activity and then to an event handler or notification activity. The dummy activity is required because it will be skipped if anything fails. The (1 sec) Wait activity is probably the easiest to use.

| If something fails the Web activity will execute |
If any of these activities above fails then the 'Dummy' Wait activity will not be executed and as a result the Web activity with the Skipped dependency will be executed. If all activities are succesful then the 'Dummy' Wait activity will be executed, but the Web activity won't .
Conclusion
In this post you learned one of the usages of the Skipped dependency, but please post your usage of the Skipped dependency in the comments below.
Note that it will wait for all 'lines' to be finished before the Dummy activity is skipped. So if Stored Procedure 1 fails then the Dummy activity still needs to wait for Stored Procedure 2, 3 and 4 to be ready (failed or succeeded). This is because the dependencies is ADF are a logial AND (in SSIS you could also change it to be a logical OR).
