Core Components of Azure Data Factory for Data Integration
Azure Data Factory (ADF) is made up of several key components that work together to perform end-to-end Azure Data Factory for data integration and transformation. Understanding these building blocks is essential to designing efficient and scalable data pipelines.
Let’s explore the main components in detail:
Pipelines
A pipeline is a logical grouping of activities that together perform a specific data task.
For example, one pipeline might copy data from an on-premises SQL Server database to Azure Data Lake Storage, while another pipeline might transform that data using Azure Databricks before loading it into Azure Synapse Analytics for reporting.
Pipelines help you organize, automate, and manage multiple data processes in a structured way.
Activities
Activities represent the individual steps within a pipeline. Each activity performs a specific operation, such as copying, transforming, or validating data.
Common types of activities include:
- Data Flow Activity: Transforms data at scale using Mapping Data Flows.
- Execute Pipeline Activity: Triggers another pipeline, allowing modular workflow design.
- Web Activity: Calls external REST APIs as part of a workflow.
By combining multiple activities, ADF enables you to design complex data processing workflows with ease.
Datasets
A dataset defines the structure and location of data used in an activity. It represents the data that serves as input or output within a pipeline. For instance, if your activity copies data from a CSV file in Azure Blob Storage to a table in Azure SQL Database, both the file and the table would be defined as datasets.
Linked Services
Linked Services act as connection configurations that define how ADF connects to data sources and destinations. They store the connection information such as credentials, endpoints, and authentication methods for services like Azure SQL Database, Azure Blob Storage, Amazon S3, or Google BigQuery. Think of linked services as the “connectors” that bridge ADF pipelines with your data environment.
Triggers
Triggers control when and how pipelines are executed. They automate pipeline runs based on predefined conditions.
Azure Data Factory supports several types of triggers:
- Schedule Trigger: Runs pipelines at specific times or regular intervals (e.g., daily, hourly).
- Event Trigger: Executes a pipeline in response to an event, such as the arrival of a new file in Blob Storage.
- Manual Trigger: Allows users or external systems to start pipelines on demand.
Triggers help automate and orchestrate data workflows efficiently.
Integration Runtime (IR)
The Integration Runtime (IR) is the compute infrastructure used by ADF to execute data flows and activities. It determines where and how data movement and transformation take place.
There are three types of Integration Runtimes:
- Azure Integration Runtime (Azure IR):
Fully managed by Azure for cloud-based data movement and transformation. - Self-Hosted Integration Runtime (Self-Hosted IR):
Installed on-premises or within a private network, enabling secure hybrid data integration between local and cloud systems. - Azure-SSIS Integration Runtime (Azure-SSIS IR):
Allows organizations to lift and shift existing SQL Server Integration Services (SSIS) packages to the Azure cloud.
The flexibility of these runtimes ensures that ADF can handle diverse integration scenarios whether entirely in the cloud, on-premises, or in a hybrid setup.
