On-object Interaction updates 

New on-object default setup is here! 

Each month we’ve been working toward giving users more flexibility in how they prefer to work with the PBI editor. This month we’re introducing a new default setup that feels closer to the previous classic look. With this new default, we’ll help you preset the following options with just one click!

  • Move the “build a visual” menu to the pane switcher by default
  • Show both build and data panes expanded by default
  • Format pane in the pane switcher by default
  • “Always open in new pane” set to ON, thereby stacking panes by default
  • Collapse panes to the pane switcher instead of close “X” by default

Upon updating to the new December build, with the new on-object preview switch ON, you’ll be greeted with a dialog to update to the new default setup. If you like your existing on-object setup and do not wish to have a more classic look, choose Keep setup and no changes will be made.

Screens screenshot of a computer Description automatically generated

If you change your mind, you can always go back to the Options menu to customize the experience to your needs. Here’s a walkthrough of what each of these options do:

  1. Suggest a type by default – If you prefer option in the Build menu to be off by default, expanding all the field wells always, make sure this is not checked.
  2. In the Build a visual menu, always show all the visualization types – If you prefer to see all the visualization types shown by default in the Build menu, be sure to check this option.
  3. Always show pane switcher – When checked, this provides the right-hand pane switcher shown even when working with zero panes. Provides access to the “+” menu and setting gear always.
  4. Always show the Build a visual menu in the pane switcher – This moves the build menu from showing next to the visual, to the pane switcher on the right side instead. Check this option if you prefer to work with the Build menu as a pane.
  5. Always open a new pane – Instead of switching between panes, check this option if you prefer the stacking behavior as before. With this option on, opening a new pane will open side-by-side by default.

To summarize, here’s the state of these settings for the new default setup:

Multi-select in data flyout

To cut down on the extra clicks when first adding data using the new “add data” button, the data flyout now allows you to multi-select fields to add fields in bulk to your visual, just like the data pane! Simply check all the fields you’d like to add to your visual in one go.

This works best when “suggest a type” is ON so you can add as many fields as you like and PBI will place the fields in the appropriate field wells for you.

In-product user education

With the many changes the on-object interaction introduced, it can hard to know where certain features may have moved. This month we’ve added four teaching bubbles to help users along the way.

  • Where’s drillthrough and tooltip page set up?
  • A teaching bubble will now point to the new location within Format > Page information.
  • Where did the analytics pane go?
  • Analytics options like error bars, max, min or percentile lines are now consolidated in the Format pane at the bottom. You can set a max, min or other reference line using the new “Reference line” card in the format pane.
  • What happened to the right click options for a field like rename or ‘show value as’?
  • They are still available at the right click! Simply right click on the field name to see the same options as before.
  • How do I bring back my data pane if the pane switcher is gone?
  • You shouldn’t run into this as frequently now that we’ve updated the behavior to collapse panes by default instead of closing. But in case you do, you can always re-open a pane from the View tab in the ribbon.

Storytelling in PowerPoint – Suggested Content

This month we’re introducing a new feature for the Power BI add-in for PowerPoint that makes it easier to find and insert the Power BI reports you need for your presentation.

When you add the Power BI add-in to your slide, the add-in automatically scans the title of the slide and suggests Power BI content that might be relevant. For example, if the title of your slide is “Holiday campaign status”, the add-in will show you a list of Power BI reports that contain data about campaigns.

The add-in also shows you reports you’ve recently visited in Power BI, so you can easily access reports you’re working on or frequently use.

Note: If the report you wanted to add doesn’t appear in the list of suggestions, you can just copy the report’s URL and paste it into the input box, as you’ve always done.

Git integration conflict resolution

When working with Git integration in Fabric, conflicts can occur if the same items are edited in both the Fabric workspace and in the connected Git repository. To avoid any mistakes, items in conflict are marked as such, and the conflicts must be resolved before any further changes can be made. In these cases, it is up to you to decide which changes to keep and which to discard.

A screenshot of a phone

Description automatically generated

To make things easier, we’ve added the option to resolve conflicts and select which content to keep directly within the Fabric workspace, so that you don’t have to navigate elsewhere or revert to previous versions.

Accessed by updating items from the source control pane, resolving conflicts is as simple as selecting whether to accept incoming changes or keep the current content for each item in conflict:

Once the selections are made, all items can be merged and updated, and any further changes can be made in the workspace.

Resolving conflicts can also be done by reverting either the workspace or the Git branch to a previous state, or directly in Git if you need to further inspect what changes were made and which version to choose. Read more on how to Resolve conflicts with Git integration – Microsoft Fabric | Microsoft Learn.

New supported items for git integration and deployment pipelines

Microsoft Fabric’s lifecycle management tools, Git integration and deployment pipelines, enable seamless communication and collaboration among all members of the development team. We are thrilled to share that we’ve expanded support for additional Fabric items across these tools.

Git integration can now be used with Notebooks and Lakehouses, in addition to the already available Reports, Paginated Reports and Semantic Models. You can back up and version your notebooks and lakehouses, revert to previous stages, collaborate, or work alone using Git branches, and manage your content lifecycle entirely within Fabric.

For deployment pipelines, we’ve added support for Notebooks and Lakehouses as well, enabling you to deploy these items across different environments such as development, test, and production and enabling you to streamline your development process.

Learn more about Lakehouse and Notebook source control and deployment to understand the capabilities of each item type within Git integration and deployment pipelines.

Changes to workspace retention settings in Fabric and Power BI

Today when a Microsoft Fabric workspace is deleted, the workspace and its contents are retained for 30 days before being permanently deleted. Starting November 15th, the retention period for collaborative workspaces will be configurable from 7 to 90 days. The workspace retention setting will be enabled by default and the default retention period will be 7 days.

Fabric administrators will be able to specify the workspace retention period in the Admin Portal. After the configured retention period, workspaces will be permanently deleted. The retention period can be modified anytime.

Fabric administrators can permanently delete workspaces that are in the retention period through Admin portal. When a workspace is permanently deleted by the Fabric administrator or automatically (after the retention period), the workspace and its contents become irrecoverable.

Fabric administrators can also restore workspaces that are in the retention period through the Admin Portal. Administrators must provide a user principle that will be assigned the workspace admin role in the recovered workspace. When a workspace is recovered, the roles and permissions associated with the workspace are not recovered.

Note that this change does not affect product behavior when a Premium or Fabric capacity is deleted. When a Premium or Fabric capacity is deleted, its workspace is moved to a Shared capacity. My Workspaces will be retained for 30 days before being permanently deleted.

Fabric administrators should review the workspace retention admin setting in Fabric admin portal. In the Fabric admin portal, go to Workspace settings > Define workspace retention period.

  1. Turn on the setting and enter the number of days for desired retention period. You can choose anywhere from 7 to 90 days.
  2. When it is done, select Apply.

Data Warehouse

Automatic Log Checkpointing

We are excited to announce automatic log checkpointing for Data Warehouses!

One of our goals with the Data Warehouse is to automate as much as possible to make it easier and cheaper for you to build and use them. This means you will be spending your time on adding and gaining insights from your data instead of spending it on tasks like maintenance. As a user, you should also expect great performance which is where log checkpointing comes in!

What is Log Checkpointing and why is it important?

To understand what log checkpointing is and why it is important, we need to first talk about how tables are stored and how they are queried.

When you create a table and add data to it, the data is stored in parquet files on OneLake. Internally, there is also a log file that keeps track of which parquet files, when combined, make up the data that is in the table. These log files are internal and cannot be used directly by other engines. Instead, we automatically publish Delta Lake Logs so that other engines can directly access the right parquet files.

Now, imagine that you load data into your table every 5 minutes. That means over the course of a year, you would have loaded data to your table 105120 times. Each time, a new log file would be created that tells the system that when reading the table, the new parquet files need to be read as well. That means when reading the table, the system first needs to read all 105120 log files which are not very performant.

This is where log checkpointing comes in! As of the time of this blog, after every 10 transactions, we automatically and asynchronously create a new log file that is called a checkpoint. This file is basically a summary of all the previous log files. Now when you query the table, the system needs to read the latest checkpoint and any log files that were created after. Instead of having to read 105120 log files, we would typically need to read 10 or less files!


Log Checkpointing is one of the ways that we help your Data Warehouse to provide you with great performance and best of all, it involves no additional work from you! This helps give you more time to work on leveraging your Data Warehouse to gain more value and insights!

Please look forward to more announcements about more automated performance enhancements!

The Art of Data warehouse recovery within Microsoft Fabric

In the ever-evolving landscape of data management, data warehouses play a pivotal role in storing and processing vast volumes of data. This enables organizations to derive meaningful insights and make well-informed data driven decisions. The necessity for a quick and reliable data warehouse recovery solution becomes increasingly crucial to not only safeguard against data corruption but also to ensure business continuity. We are thrilled to launch the ability to perform the restore in-place of the data warehouse within Microsoft Fabric.

Restore in-place is an essential part of data warehouse recovery which allows to restore the data warehouse to a prior known reliable state by replacing or over-writing the existing data warehouse from which the restore point was created. Restore points are recovery points that can be leveraged to restore the data warehouse. From the moment the data warehouse is created, system generated restore points are created every 8 hours.  There will be a total of 42 system generated restore points at any given point in time.

Furthermore, you have the flexibility to create any number of user-defined restore points aligned with your specific business or organizational recovery strategy.  Both the system-generated and user-defined restore points come with a retention period of seven calendar days, after which they will expire.

In an era where resilience of data aligns with resilience of business, having a well-established restore plan for data warehouse is critical for organizations. Explore the capability to perform restore in-place using Rest API.

Two new code snippets are now available as part of PySpark Notebooks to help you read data from a KQL Database and write data to it.

Write data to KQL Database (Kusto): like reading, write data snippet allows you to create PySpark code to write read data to a KQL Database. All you need to provide is KQL Database URI, database name and table.

Semantic Link Update

We’re excited to announce the latest update of Semantic Link! Apart from many improvements we also added many new features for our Power BI engineering community that you can use from Fabric notebooks to satisfy all your automation needs.



Real-time Analytics

Enabling Data Availability of KQL Database in OneLake

Enabling data availability of KQL Database in OneLake means customers can enjoy the best of both worlds:

  • They can query the data with high performance and low latency in their KQL database.
  • Query the same data in Delta Parquet via Power BI Direct Lake mode, Warehouse, Lakehouse, Notebooks and more.

This capability is part of the one logical copy promise in Fabric. It is important to note that users will only be charged once for the data storage. No extra charge is required once the data is made available also in Delta Parquet format.

Enabling the feature is quite simple. All that is needed is for the user to enable the Data Availability option of the selected KQL Database. Read this blog for more information.

Create a Notebook with pre-configured connection to your KQL DB

You can now just create a new Notebook from KQL DB editor with a pre-configured connection to your KQL DB and explore the data using PySpark. This option creates a PySpark Notebook with a ready-to execute code cell to read data from the selected KQL DB.

KQL Database schema validation

Like any piece of code, your database schema is as good as the intent you convey when you wrote it.  But over time, the intent diffuses, and different priorities, authors and just plain miscommunication can diminish the quality of your code.

The new Kusto command. show database schema violations was designed to validate the current state of your database schema and find inconsistencies.

  • Does the function associated with an update policy still have the same schema as the target schema or do the two drift away?
  • Function A calls Function B which calls Function C: Does Function B still exist?  Is the schema of each output chain in a consistent manner?
  • Does your materialized view source table still exist?  Is the schema compatible?
  • Etc.

The command returns a table with schema validation issues.  Since that is a KQL query result set, you could filter / format it using usual KQL query capabilities.

You can use this command for a spot check on your database.  You could also use it in CI/CD automation: for instance, you could validate your schema in a dev environment before deploying the schema to production, as a quality gate.

Calculating distinct counts in Power BI running reports on KQL Databases

Calculating distinct counts on massive, distributed datasets is not trivial. Fabric KQL database dcount and dcountif functions use a special algorithm to return an estimate of distinct counts , even in extremely large datasets.

The new functions count_distinct and count_distinctif were recently added to calculate exact distinct counts. These two functions are much more expensive than the original ones.

To bridge the gap between these two approaches, we added a setting in Power BI to control the level of accuracy of dcount. This will allow users to optimize the accuracy of the dcount function vs the runtime of the query. The setting also allows calling count distinct when absolute accuracy is needed.

Data Factory

Data pipelines

Azure Databricks Activity

You can now create powerful data pipeline workflows that include Notebook executions from your Azure Databricks clusters using Fabric Data Factory. Add a Databricks activity to your pipeline, point to your existing cluster, or request a new cluster, and Data Factory will execute your Notebook code for you!

Connection editing in pipeline editor now supported

You can now edit your existing data connections while you are designing your pipeline without leaving the pipeline editor!

When setting your connection, simply click Edit and a pop up will appear.

Read and Write to the Fabric Lakehouse using Azure Data Factory (ADF)

You can now read and write data in the Microsoft Fabric Lakehouse from ADF (Azure Data Factory). Using either Copy Activity or Mapping Data Flows, you can read, write, transform, and process data using ADF or Synapse Analytics, currently in public preview.

Set activity state for easy pipeline debugging

In Fabric Data Factory data pipelines, you can now set an activity’s state to inactive so that you can save your pipeline even with incomplete, invalid configurations. Think of it as “commenting out” part of your pipeline code.
