Azure Data Factory Framework Essentials for Data Professionals are crucial for anyone working with data.
Azure Data Factory (ADF) is a cloud-based data integration service that allows you to create, schedule, and manage data pipelines.
It's built on a cloud-scale, highly available, and secure architecture that enables you to integrate with various data sources and destinations.
ADF supports a wide range of data sources and destinations, including Azure Blob Storage, Azure SQL Database, and Amazon S3.
Data professionals can use ADF to automate data processing and movement, reducing manual effort and improving data quality.
Key Features
The Azure Data Factory framework is a powerful tool for ingesting and orchestrating large amounts of data. More than 90 built-in connectors are available to help you get started.
Orchestrating and monitoring data at scale is a complex task, but with Azure Data Factory, you can do it efficiently.
One of the key benefits of Azure Data Factory is its ability to handle a wide range of data sources, including on-premises and SaaS data.
Integration and Orchestration
Azure Data Factory is a fully managed, serverless data integration service that integrates all your data with more than 90 built-in, maintenance-free connectors at no added cost. You can easily construct ETL (extract, transform, and load) and ELT (extract, load, and transform) processes code-free in an intuitive environment.
Azure Data Factory supports various control flow activities, including Append Variable, Execute Pipeline, Filter, For Each, Get Metadata, If Condition Activity, Lookup Activity, Set Variable, Until Activity, Validation Activity, Wait Activity, Web Activity, and Webhook Activity. These activities enable you to implement complex data pipelines with ease.
Here are some key features of Azure Data Factory's control flow activities:
Integration and Orchestration with Azure Synapse
Azure Synapse is a unified analytics platform that enables comprehensive data consolidation, processing, and analytics. It provides a robust data integration service that can be used to expedite data exploration and management.
With Azure Synapse, you can ingest data from diverse and multiple sources, including on-premises, hybrid, and multicloud sources, and transform it with powerful data flows. This is made possible through the use of over 90 built-in connectors, which can be used to acquire data from various sources such as Amazon Redshift, Google BigQuery, and Hadoop Distributed File System (HDFS).
Azure Data Factory is a fully managed, serverless data integration service that can be used to integrate all your data with Azure Synapse. It provides a visually intuitive environment where you can construct ETL (extract, transform, and load) and ELT (extract, load, and transform) processes code-free.
One of the key benefits of using Azure Data Factory is its ability to simplify hybrid data integration at an enterprise scale. It provides a data integration and transformation layer that works across your digital transformation initiatives, empowering citizen integrators and data engineers to drive business and IT-led analytics/BI.
Here are some of the key features of Azure Data Factory:
- More than 90 built-in connectors for ingesting all your on-premises and software as a service (SaaS) data
- Ability to construct ETL and ELT processes code-free
- Support for automated copy activities
- Ability to monitor all activity runs visually and set up alerts proactively to monitor pipelines
- Integration with Azure Synapse Analytics to unlock business insights
By using Azure Synapse and Azure Data Factory, you can exploit Azure's sophisticated data integration features, enhancing the efficiency and intelligence of your data processes.
Control Flow Activities
Control Flow Activities are the backbone of any integration and orchestration pipeline. They determine the order in which activities are executed and provide a way to control the flow of data.
There are several types of Control Flow Activities, including Append Variable, Execute Pipeline, Filter, and For Each. Each of these activities serves a specific purpose, such as adding a value to an existing array variable or executing a pipeline.
The For Each activity, for example, is used to iterate over a collection and execute specified activities in a loop. This is similar to the Foreach looping structure in programming languages.
Control Flow Activities can also be used to define activity dependencies, which determine the condition of whether to continue executing the next task. There are four dependency conditions: Succeeded, Failed, Skipped, and Completed.
Here's a breakdown of the dependency conditions:
These dependency conditions can be used to create complex workflows and ensure that activities are executed in the correct order.
Control Flow Activities are a powerful tool for integrating and orchestrating data pipelines. By using these activities, you can create complex workflows that can be executed in a specific order, ensuring that data is processed correctly and efficiently.
Security and Compliance
In Azure Data Factory, robust security features ensure your data is protected. Azure Data Factory's advanced security and privacy features include column- and row-level security.
This means you can control who sees what data, making it easier to meet compliance requirements. Column-level security allows you to restrict access to specific columns of data, while row-level security restricts access to specific rows.
Pipeline Management
Scheduling pipelines is a crucial part of Azure Data Factory. Pipelines are scheduled by triggers, which can be either Scheduler triggers or manual triggers.
You can have multiple triggers kick off a single pipeline, and the same trigger can kick off multiple pipelines. This is an n-m relationship between pipelines and triggers.
To kick off a pipeline run, you must include a pipeline reference in the trigger definition. This means specifying the particular pipeline you want to trigger.
For example, if you have a Scheduler trigger called "Trigger A" that you want to kick off your pipeline "MyCopyPipeline", you would define the trigger with the pipeline reference.
Monitoring pipeline performance is also essential. You can monitor all your activity runs visually and set up alerts proactively to prevent downstream or upstream problems.
This can be done within Azure Data Factory, where you can see all your activity runs and set up alerts that appear within Azure alert groups.
Maintaining pipelines can be time-consuming, but Azure Data Factory helps you streamline your data pipelines. This enables efficient data ingestion, transformation, and loading processes.
By using Azure Data Factory, you can transition your on-premises data workflows to the cloud and fully harness its capabilities for orchestrated data movement and transformation.
Frequently Asked Questions
What is the structure of Azure Data Factory?
Azure Data Factory consists of four key components that work together to define data flow: Datasets, which represent data structures within data stores, and three other components that manage input, processing, and scheduling. These components enable efficient data processing and movement in Azure Data Factory.
What is the technology behind Azure Data Factory?
Azure Data Factory uses a Spark cluster to run data flows at scale, handling large datasets without requiring manual setup or tuning. This scalable technology enables efficient data transformation, making it a powerful tool for data processing.
Which 3 types of activities can you run in Microsoft Azure data Factory?
In Azure Data Factory, you can run three main types of activities: data movement, data transformation, and control activities. These activities enable seamless data integration and processing in the cloud.
