Can wskdeploy orchestrates actions as a DAG?

Hi there,

I want to build a DAG job in openwhisk by using wskdeploy.

I know wskdeploy can create a sequence, but can wskdeploy create a DAG job?

suppose there are 4 DAG functions in a workflow, the relationship of the 4 functions is floowing:

A --> B ——>D
 ↘   ↗
   C

That is, function `A` sends the same outputs to function `B` and function `C`.

Note that functions `B` and function `C` can be executed in parallel (for different purposes).

function `C` receives the output of the function `A` and sends the output to function `D`.

Here, function `D` will not be executed until it receives both inputs from function `B` and function `C`.

I think it is a common demand in real-world workflow, could anyone tell me how to do this?

Start by reviewing wskdeploy's existing sequence support and how OpenWhisk represents workflows. Determine whether branching, parallel execution, and joining both inputs are supported, then document the supported approach or define the implementation scope and acceptance criteria for DAG orchestration.
