This section describes Google Cloud options you can use to schedule
workflows.
Dataproc Workflow Templates
DataprocWorkflow templatesprovide a flexible and easy-to-use mechanism for managing and executing workflows. A Workflow Template is a reusable workflow configuration. It defines a graph of jobs with information on where to run those jobs.
Cloud Scheduler
Cloud Scheduler is a fully managed enterprise-grade cron job scheduler.
It allows you to schedule virtually any job, including batch, big data jobs,
and Cloud infrastructure operations. It provides simple time-based
scheduling, for example, daily or hourly, without requiring you to write code.
Advantages:
Enables time-based instantiation of workflow templates based on familiar
cron expressions
Cloud Run functions is a lightweight compute solution you can use to create
single-purpose, stand-alone functions that respond to Cloud events without
the need to manage a server or runtime environment. You can use
Cloud Run functions to launch Workflows in response to Pub/Sub
events or file changes in Cloud Storage. You can use Cloud Run functions
with Cloud Scheduler for workflows that require the calculation of
time-based parameters.
Advantages:
Enables workflow instantiation in response to data events, such as new files in
Cloud Storage or Pub/Sub events.
Minimal coding required using DataprocGo,Node.js, orPythonclient libraries
Dynamically generate workflows and workflow parameters
