This module demonstrates an event-driven workflow for detecting water bodies in Sentinel-2 satellite imagery using Argo Events, Argo Workflows, and Calrissian.

It utilizes a Redis stream to trigger workflows that process Sentinel-2 imagery and generate outputs using CWL (Common Workflow Language).

Argo Workflows is a Kubernetes-native workflow engine that lets you define and run multi-step processes in the form of Directed Acyclic Graphs (DAGs).

Each "step" in a workflow can be a container or an operation, enabling automation of complex tasks like data processing, ETL jobs, or ML model training.

Argo Events is an event-driven automation framework for Kubernetes. It allows workflows and other tasks to be triggered in response to various events, such as webhooks, message queues, or timers.

By connecting event sources (like a Redis stream) to sensors that listen for events, you can trigger automated workflows.

The module involves:

• Event Source: A Redis stream that holds Sentinel-2 image acquisitions.
• Sensor: Listens for events from the Redis stream and triggers a workflow to detect water bodies.
• Argo Workflow: Executes a CWL-based workflow using Calrissian to process Sentinel-2 images.
• Calrissian: An execution engine for running CWL workflows in Kubernetes, integrated with Argo Workflows.
