Task Flows in Microsoft Fabric: A Comprehensive Guide

In the rapidly evolving world of data analytics, the ability to visualize and manage complex workflows is crucial. This is where task flows in Microsoft Fabric come into play. Designed for data analytics solution architects and engineers, task flows provide a powerful and flexible way to manage your data analytics projects. This article aims to provide a comprehensive guide to understanding and effectively using task flows in Microsoft Fabric. Whether you’re a seasoned data professional or just starting in the field, this guide will equip you with the knowledge and skills to leverage the power of task flows in your data analytics projects.

What is Task Flow in Microsoft Fabric?

Task flows in Microsoft Fabric is a workspace feature that enables you to build a visualization of the flow of work in the workspace. It consists of a collection of connected tasks representing relationships in a process or a collection of processes that complete an end-to-end data solution. Each task is a unit of process within the task flow and has recommended item types to help you select the appropriate items when building your solution. Each task also has a task type that is classified based on its key capabilities in the data process flow.

Why Task Flows was introduced in Microsoft Fabric?

Before the introduction of task flows in Microsoft Fabric, when designing a data project, teams often had to use a whiteboard or other external tools to sketch out the different parts of the project and their interrelationships. This could be time-consuming and inefficient, especially for complex projects with many interconnected parts.

Task flows were introduced in Microsoft Fabric to address these challenges:

1. They provide a workspace feature that enables you to build a visualization of the flow of work in the workspace.

2. This helps you understand how items are related and work together in your workspace

3. It is easy to navigate your workspace, even as it becomes more complex over time.

4. Task Flows can help standardize your team’s work and keep your design and development work in sync to boost the team’s collaboration and efficiency.
   

Benefits:

1. Understanding Relationships: Task flows help you understand how items are related and work together in your workspace.

2. Standardization: Task flows can help standardize your team’s work and keep your design and development work in sync, boosting the team’s collaboration and efficiency.

3. Predefined Task Flows: Microsoft Fabric provides a range of predefined, end-to-end task flows based on industry best practices making it easier to start with your project.

4. Customization: You can customize the task flows to suit your specific needs and requirements, enabling you to create a tailored solution that meets your unique business needs and goals.

Task Types

Classification of the task based on its key capabilities in the data process flow.

1. General: This task type allows you to create a customized task for your project needs you can assign available item types. It provides flexibility and adaptability in your task flow. For example, you might use a General task to perform a custom operation that doesn’t fit other task types, such as sending an email notification when a certain condition is met in your data.

2. Get Data: This task type ingests batch and real-time data into a single location within your Fabric workspace. It supports various data sources and formats to consolidate and manage your data. For instance, you might use a Get Data task to ingest sales data from a SQL Server database, customer data from a CSV file, and real-time streaming data from a website.

3. Store Data: This task type organizes, queries, and stores your ingested data in an easily retrievable format. It supports various storage systems, allowing you to choose the best fits your project needs. For example, you might use a Store Data task to store your ingested data in Azure Blob Storage or Azure Data Lake Storage.

4. Prepare Data: This task type is used to clean, transform, extract, and load your data for analysis and modeling tasks. It supports various data preparation techniques and ensures data is ready for analysis and modeling. For instance, you might use a Prepare Data task to remove null values, normalize data, or perform feature engineering for a machine learning model.

5. Analyze and Train Data: This task type is used to propose hypotheses, train models, and explore your data to make decisions and predictions. It supports various data analysis and machine learning techniques, enabling you to gain valuable insights from your data. For example, you might use an Analyze and Train Data task to train a machine learning model to predict future sales based on your prepared data.

6. Track Data: This task type monitors your streaming or nearly real-time operational data, and makes decisions based on gained insights. It supports various data tracking and monitoring techniques, helping you keep track of your data in real time. For instance, you might use a Track Data task to create a dashboard that visualizes the performance of your sales prediction model in real time.

Working with Task Flows

Here are step-by-step guides on how to create tasks in Microsoft Fabric.

STEP 1: Navigate to the workspace where you want to create your task flow.

The workspace view is split between the task flow, where you will build your task flow, and the items list, which shows you the items in the workspace.

STEP 2: You can start with a predefined task flow or custom task flow.

Click on "Select a task flow". A list of predefined Microsoft Fabric task flows will appear. When you select one of the flows, you’ll see a more detailed description of how to use it and the workloads and item types the flow requires.

STEP 3: Select the task flow then choose ‘Select’. The selected task flow will be applied to the task flow canvas.

Add Task to the Task flow canvas

To add a new task to the task flow canvas, open the "Add" dropdown menu and select the desired task type. The task of the selected task type is added onto the canvas.

Change Task Type

Each task in a task flow has a specific type that classifies it based on its key capabilities in the data process flow. If you want to change a task type, select the task on the canvas to open the task details pane.

Open the ‘Task type’ dropdown menu and choose the new desired task type.

Arrange Tasks on the Canvas

The arrangement of tasks should illustrate the logic of the project. Select and drag each task to the desired position in the task flow.

Connecting the Tasks

To connect tasks, select a task and drag the connector (the arrow at the edge) to another task. This creates a directional link from the first task to the second, indicating the workflow.

Editing Task Name and Description

Click on the task and click "Edit" in the task details pane.

You can change the name and description fields as desired.

Once you have made your changes, click "Save" to apply the changes.

Examples where Task Flows in Microsoft Fabric can be used

Marketing Analytics Project: A marketing team wants to analyze their campaign data to optimize their marketing strategies. They could set up a task flow in Microsoft Fabric as follows:

• Get Data Task: Ingest campaign data from various sources like social media platforms, email marketing tools, and CRM systems.

• Store Data Task: Store the ingested data in Azure Blob Storage for easy retrieval.

• Prepare Data Task: Clean and transform the data, such as removing outliers, handling missing values, and encoding categorical variables.

• Analyze and Train Data Task: Use machine learning models to analyze the data and predict campaign outcomes.

• Track Data Task: Monitor the performance of the campaigns in real time and make adjustments based on the insights gained.
