Azure Data Factory V2 Dependencies

Meagan Longoria has important notes on how Azure Data Factory V2 Dependencies differ from SQL Server Integration Services precedent constraints:

This sounds similar to SSIS precedence constraints, but there are a couple of big differences.

  1. SSIS allows us to define expressions to be evaluated to determine if the next task should be executed.
  2. SSIS allows us to choose whether we handle multiple constraints as a logical AND or a logical OR. In other words, do we need all constraints to be true or just one.

ADF V2 activity dependencies are always a logical AND. While we can design control flows in ADF similar to how we might design control flows in SSIS, this is one of several differences. Let’s look at an example.

Meagan gives us three methods of replicating SSIS functionality using ADF V2, so check it out.
