Change Data Capture Overview
What Is Change Data Capture
You want your data to stay current. You do not want to move everything each time. Change Data Capture helps with this. It finds and records changes in a database. You can track inserts, updates, and deletes as they happen. These changes go to other systems right away. You do not need to reload all your data. You just use a list of changes called a CDC feed. This way saves time and uses fewer resources.
Tip: With Change Data Capture, you only work with what changed. You do not have to move all your data every time.
Why It Matters
Change Data Capture is important for modern data work. You want your reports to show the newest information. CDC sends updates as soon as they happen. Here are some ways to use CDC:
ETL for data warehousing: Move only new or changed data. This makes ETL jobs faster.
Real-time analytics and reporting: Get fresh insights for better choices.
Cloud migration and hybrid sync: Keep cloud and on-premises data matched with no downtime.
Data lakehouse hydration: Send new data to your lakehouse for analytics and data science.
Real-time fraud detection: Find and stop suspicious activity quickly.
Real-time marketing campaigns: Change your marketing based on the latest customer actions.
You get more benefits too:
CDC tracks changes right away, so your data matches across systems.
You only move new data, so pipelines work faster and better.
Your business teams get correct and quick data for reports and analytics.
You avoid problems like lost money, bad choices, and high costs from old data.
Keeping your data fresh and matched helps you make smart choices and keeps your business working well.
Microsoft Fabric CDC Features
Real-Time Hub
The Real-Time Hub in Microsoft Fabric helps you connect data sources fast. This hub is the main spot to set up and manage Change Data Capture. You do not need to write code or do hard setups. The Real-Time Hub has connectors for many data types. You can bring in data from different places with a few clicks.
After you connect your sources, you can change your data streams. You can filter out data you do not want. You can group records or mix streams together. You can also send your data to a KQL database. This lets you run quick searches and get answers fast. If you want to act when something changes, you can set up alerts. The system will watch for certain things and do actions, like sending a message or updating a dashboard.
Here is a simple look at what the Real-Time Hub gives you:
Tip: The Real-Time Hub keeps your data fresh and ready for analysis. You do not have to do extra work.
Automated Data Streams
Automated data streams mean you do not move data by hand. Microsoft Fabric makes pipelines that catch changes as they happen. This means you always use the newest data. The system checks for new inserts, updates, or deletes. It only moves what changed. You save time and avoid mistakes from doing things by hand.
Automated streams help you handle more data. You can work with lots of data without slowing down. The platform adds more power if you need it. You do not have to worry about speed. You also get better error handling. If something goes wrong, the system finds and fixes it early.
Here is how automated data streams are different from manual work:
You can trust your Change Data Capture process will stay fast, correct, and simple to use.
Setting Up Change Data Capture
Setting up Change Data Capture in Microsoft Fabric is easy. You follow simple steps to connect your data. You can organize streams and watch everything in one spot. This guide shows you each step. You keep your data current with less work.
Prerequisites
Before you begin, check your setup. You need Microsoft Fabric access. You must have permission for the Real-Time Hub. Your data sources should be ready. Microsoft Fabric works with many databases and cloud services.
Here are some supported data sources:
Know your source and target locations. This helps you finish setup faster.
Tip: Set up your linked services before you start. This saves time when you set things up.
Source Configuration
Start by going to the Author pane in your data factory. Look under Pipelines for Change Data Capture (preview). Hover and click Actions, then pick New CDC (preview). This opens a step-by-step setup.
Follow these steps:
Give your CDC resource a name. Use the default or make your own.
Pick your data source from the list. For example, choose DelimitedText for text files.
Select or make a linked service for your source.
Change source settings if you need, like column and row marks.
Find and pick your source data folder.
Click Continue to choose your data target.
Pick a target type, like Azure SQL Database.
Select or make a linked service for your target.
Choose your target tables. You can pick more than one.
Click Continue to go to the CDC studio.
Check and change column matches. The system matches columns for you, but you can fix them.
The setup uses a simple screen and easy steps. You do not need to write code or use hard scripts. The system helps you link your sources and targets fast.
Stream Cataloging
After setup, you can organize your data streams in the Real-Time Hub. The hub is your main place for streaming data. You can find, manage, and use data as it moves.
The Real-Time Hub helps you find and sort all your streaming and event data.
You can search for streams and KQL database tables quickly.
The hub organizes your data, so you can use it in other Fabric tools.
You can act on new data right away, using Reflex or sending data to Eventhouse for deeper checks.
The Real-Time Hub makes it simple to track your moving data. You always know where your streams are and how to use them.
Monitoring
You can watch your Change Data Capture events with built-in tools in Microsoft Fabric. These tools help you see changes and keep your data fresh.
You can also set alerts and automatic actions. The system can try failed jobs again and send messages if something goes wrong. This means less manual work and faster fixes.
With Microsoft Fabric, you get automation and monitoring together. You spend less time checking your data and more time using it.
Setting up Change Data Capture in Microsoft Fabric is much easier than old ways. You get step-by-step setup, automatic matching, and strong monitoring tools. You can focus on your data, not on the setup.
Integrating and Automating with Fabric
Data Activator
You can use Data Activator in Microsoft Fabric to turn real-time data into instant business actions. Data Activator watches your data streams and looks for important changes. When it finds something you care about, it acts right away. You do not need to check your data all the time. Data Activator uses reflexes, which are rules that respond to certain events or values in your data. For example, you can set a rule to alert you if a delivery takes too long or if sales drop below a target.
Here is how you set up Data Activator with your Change Data Capture streams:
Open the Explorer pane and select your data stream.
Create a new object, such as a package or order, and choose the unique ID and properties you want to track.
Build a rule that watches for a specific condition, like a value going above or below a threshold.
Choose what happens when the rule is met, such as sending an email or a Teams message.
Test your rule to make sure it works, then start it.
Data Activator helps you catch problems early and respond fast. You save time and avoid mistakes.
Triggering Actions
With Microsoft Fabric, you can trigger many types of actions based on data changes. When a Change Data Capture event happens, you can:
Start a pipeline when a new file appears in storage.
Update inventory systems in near real-time.
Run notebooks to train models using the latest data.
Send alerts or messages to your team.
You can connect these actions across different services without extra setup. Fabric keeps your data current and your processes running smoothly.
Best practices for seamless integration:
Design for change. Expect your data to evolve and use tools that detect changes.
Build event-driven pipelines. This helps your system scale as your needs grow.
Capture data once and share it with many users.
Monitor your system and check data quality often.
Make sure your data is secure and easy to audit.
When you follow these steps, you create a system that is fast, reliable, and ready for anything.
Microsoft Fabric makes Change Data Capture easy and strong. You can link systems together. You can make reports faster. Your data stays up to date. Teams get many good things:
You can work better, grow easily, and match data almost right away.
