Action nodes are the mechanism by which a workflow triggers the execution of a task. Orchestration frameworks are often ignored and many companies end up implementing custom solutions for their pipelines. Remember, tasks and applications may fail, so you need a way to schedule, reschedule, replay, monitor, retry and debug your whole data pipeline in an unified way. Please make sure to use the blueprints from this repo when you are evaluating Cloudify. It then manages the containers lifecycle based on the specifications laid out in the file. Jobs orchestration is fully integrated in Databricks and requires no additional infrastructure or DevOps resources. When possible, try to keep jobs simple and manage the data dependencies outside the orchestrator, this is very common in Spark where you save the data to deep storage and not pass it around. Most peculiar is the way Googles Public Datasets Pipelines uses Jinga to generate the Python code from YAML. It has integrations with ingestion tools such as Sqoop and processing frameworks such Spark. Dynamic Airflow pipelines are defined in Python, allowing for dynamic pipeline generation. Instead of directly storing the current state of an orchestration, the Durable Task Framework uses an append-only store to record the full series of actions the function orchestration takes.
