Why Data Matters?

In today’s digital age, data-driven insights are crucial for the success of every business, regardless of its size or industry. Here’s why:

  1. Informed Decision Making: Data-driven insights provide businesses with factual evidence, enabling them to make informed decisions. This reduces the risk of making decisions based on intuition or gut feelings.

  2. Identifying Trends and Patterns: With data-driven insights, businesses can identify trends and patterns in their operations. This can help in predicting future outcomes and making proactive decisions.

  3. Improving Efficiency: Data can highlight areas of inefficiency in a business, allowing for targeted improvements. This can lead to cost savings and improved productivity.

  4. Understanding Customers: Data can provide valuable insights into customer behavior and preferences. This can inform marketing strategies and help businesses to better meet the needs of their customers.

  5. Competitive Advantage: Businesses that leverage data effectively can gain a competitive advantage. They can identify growth opportunities, predict market trends, and stay ahead of their competitors.

The Problem

Modern businesses generate and store data across various applications, databases, and data warehouses. This fragmented landscape presents several challenges:

  • Data Fragmentation: Data residing in disparate locations like apps, databases, and data warehouses leads to fragmentation. Each source may have unique structures and formats, hindering a unified view of the data.

  • Cross-Referencing Complexity: Analyzing and cross-referencing data from various sources is a complex task requiring significant effort to ensure compatibility and conduct meaningful analysis.

  • Resource-Intensive Integration: Moving and harmonizing large-scale data is a time-consuming and resource-intensive endeavor. The traditional ETL (Extract, Transform, Load) process requires specialized skills and consumes substantial financial resources.

These challenges impede businesses from fully leveraging their data for insights and strategic decision-making.

The Solution: Mirroring in Microsoft Fabric

Mirroring is a feature in Microsoft Fabric that simplifies accessing and ingesting data. It addresses the challenges of data fragmentation and the difficulty in cross-referencing data from different sources. With Mirroring, any database can be accessed and managed from within Fabric. Your database is instantly available in Fabric as a Mirrored database by providing connection details,

The benefits of using Mirroring are numerous:

  1. Speed: Mirroring provides real-time data replication. An initial snapshot is created, after which data is kept in sync in near real-time with every transaction.

  2. Safety: Mirroring uses the source database’s Change Data Capture (CDC) technology, ensuring that data is updated continuously and safely.

  3. Elimination of Cumbersome Pipelines: With Mirroring, there is no need for complex setup or ETL (Extract, Transform, Load) processes. This eliminates the need for cumbersome data pipelines, saving time and resources.

How does it work?

Mirroring in Microsoft Fabric is designed to simplify accessing and managing data. Your database can be securely accessed and managed centrally from within Fabric. This means you can interact with your data directly from Fabric, without switching between different database clients.

Setting Up Mirroring

To set up mirroring in Microsoft fabric, it involves two main steps:

  1. Enable mirroring for your tenant

  2. Enable mirroring for specific capacity

Enable Mirroring for your tenant:

  • Navigate to the tenant settings in the admin portal and in Microsoft Fabric, expand Mirroring (preview).

  • Enable the Mirroring (preview) switch.

  • (Optional) Use the Specific security groups option to enable Mirroring for specific users. You can also use the Except specific security groups option, to enable Mirroring for the tenant, and exclude specific users.

  • Select Apply.

Enable Mirroring for a specific capacity:

  • Navigate to the capacity settings in the admin portal in Microsoft Fabric.

  • Select the capacity where you want to enable Mirroring.

  • Select the Delegate tenant settings tab.

  • Expand the Mirroring (Preview) setting.

  • Check the Override tenant admin selection checkbox and verify that the Mirroring (preview) setting is enabled.

  • (Optional) Use the Specific security groups option to enable Mirroring for specific users. You can also use the Except specific security groups option, to enable Mirroring for the capacity, and exclude specific users.

  • Select Apply.

The ability to access and manage any database centrally from within Fabric is a key component of Mirroring. This feature eliminates the need for switching between different database clients, thereby simplifying the process of data management. It also ensures that your data is securely accessed and managed, providing you with peace of mind.

Real-Time Data Replication

Mirroring in Microsoft Fabric offers real-time data replication, which is a key component of its architecture.

Simplified Data Replication

The process of data replication with Mirroring is straightforward and requires no complex setup or ETL (Extract, Transform, Load) processes. This simplifies the traditionally complex task of data replication, making it accessible to a wider range of users.

Continuous Updates

Mirroring ensures that data is updated continuously and kept in sync in near real-time. This means that any changes made to the source data are immediately reflected in the mirrored data. This real-time synchronization allows for up-to-date analysis and decision-making.

Change Data Capture (CDC) technology

Mirroring utilizes the source database’s Change Data Capture (CDC) technology. CDC identifies and captures changes made in the source database and applies them to the target database. This ensures that the mirrored data is always an accurate reflection of the source data.

Granular Controls

Mirroring provides granular controls, allowing businesses to configure which data gets mirrored into Fabric. This lets you focus on mirroring only the data relevant to your analytics needs, optimizing resource usage, and boosting efficiency

Here are some of the granular controls that are available:

  1. Data Selection: You can choose which specific data (like tables or entities) you want to be reflected in Fabric. This allows you to focus on the most relevant information for your analysis.

  2. Monitoring: Detailed monitoring capabilities are available to gain insights into mirroring operations. This includes information on when the replica in Fabric OneLake was last refreshed.

  3. Security Groups: You can use the Specific security groups option to enable Mirroring for specific users. You can also use the Except specific security groups option, to enable Mirroring for the tenant, and exclude specific users.

Data Warehousing Experiences Simplified

Every Mirrored database comes with default data warehousing experiences via an SQL Analytics Endpoint. This endpoint houses the metadata of the Delta tables and points to the data in OneLake.

This means that once your data is mirrored into Fabric, you can immediately start querying and analyzing your data using SQL Analytics Endpoint. You don’t need to worry about setting up a separate data warehouse or managing the transfer of data between your database and the data warehouse.


Microsoft Fabric Mirroring presents a compelling solution for businesses struggling with data fragmentation and complex data management processes. By centralizing data access, ensuring real-time replication, and offering simplified analytics experiences, Fabric Mirroring empowers organizations to unlock the true potential of their data. This translates to informed decision-making, optimized resource allocation, and a significant competitive advantage in today's data-driven world. If you're looking to streamline data management and gain valuable insights from your information, Microsoft Fabric Mirroring is a powerful tool waiting to be explored.
