Linked Services

Linked services establish connections to external data stores. They encapsulate connection information and credentials, enabling ADF to access and retrieve data from different sources securely.

Pipelines

Pipelines define the workflow of data processing tasks. They orchestrate activities such as data movement, transformation, and more. Pipelines provide a structured approach to designing and automating data workflows.

Activities

Activities are the building blocks of pipelines, representing individual data processing steps. They include copying data, executing transformations, and running custom scripts.

Data Flow

Data Flow is a visual design interface within ADF for building ETL (Extract, Transform, Load) processes. It offers a range of transformations and data manipulation capabilities to transform raw data into actionable insights.

Triggers

Triggers initiate the execution of pipelines based on predefined events or schedules. They allow automated execution of pipelines at specific times, recurrence intervals, or in response to external triggers.

Integration Runtimes

Integration runtimes serve as execution environments for data movement and transformation. They can be configured to run on Azure or on-premises, enabling ADF to interact with diverse data sources.

Linked Services and Datasets Mapping

This mapping establishes the association between linked services and datasets, allowing datasets to reference specific data sources through linked services.

Monitoring and Logging

ADF provides monitoring capabilities to track pipeline executions, monitor activity runs, and diagnose issues. It offers insights into execution status, data movement, and transformation performance.

Parameters and Variables

Parameters and variables enable dynamic behavior within pipelines. It allow for flexibility in defining pipeline properties, while variables store and manage values during pipeline execution.

Creating and Managing Pipelines in ADF

Creating and managing pipelines in Azure Data Factory (ADF) is crucial to efficient data integration. Pipelines define data flow and operations within ADF, orchestrating data movement and transformation. Here’s a concise guide to the key steps in creating and managing pipelines within ADF.
