i want to send DAG information relationship between steps to another service for tracking currently without flyte all my steps has a base class so at compile time i construct a graph with information about the relationship between steps When it s migrated to flyte i no longer use a base class and steps are reference workflows now what s the best way to send the DAG information

Melody Lui · Answer

would i be able to create a workflow decorator <https docs flyte org projects cookbook en latest auto examples advanced composition decorating workflows html|flyte doc> to get the dag information at compile time and create a node that sends the tracking information
