Azure Data Factory: Fail Activity

Azure Data Engineering

During some scenarios in Azure Data Factory, we may want to intentionally stop the execution of the pipeline. An example could be when we want to check the existence of a file or folder using Get Metadata activity. We may want to fail the pipeline if the file/folder does not exist. To achieve this, we could use the Fail Activity. Invoking the Fail Activity ensures that the pipeline execution will be stopped.

Azure Data Factory: Wait Activity

Azure Data Engineering

In one of the previous posts, we discussed how we can use Validation activity to design the Pipeline to wait for a scheduled time and retry. There is another way to introduce a delay in the Pipeline. Wait activity can be used to pause the execution of the Pipeline for a fixed amount of time. Sometimes, we come across scenarios where we would like the execution for the Pipeline to be Paused for some time but not cancelled.
