Performance improvement in Salesforce connector in data pipelines

Salesforce is a critical data source for many organizations, housing valuable customers and business data. To enhance data movement efficiency, Data Factory has introduced performance optimization in the Salesforce connector for pipelines. Optimization allows you to fetch the data concurrently from Salesforce by leveraging the parallelism capability, thus significantly reducing extraction times for large datasets.

Lakehouse connector now supports deletion vector and column mapping for delta tables in data pipelines.

The Lakehouse connector in Data Factory has been upgraded to provide deeper integration with delta table. Two major new capabilities enhance data processing workflows:

1. Support for deletion of vector

Delta table uses deletion vectors to track deleted records efficiently without physically removing them from storage. With this new feature in the Lakehouse connector, users can:

Read Delta tables while respecting deletion vector, ensuring that deleted records are automatically excluded from queries.
Improve performance by leveraging soft deletions instead of physical file modifications, making data updates and maintenance more efficient.
Enable compliance with data retention policies by retaining historical data for auditability while ensuring deleted records are filtered out from active queries.

2. Column mapping support for delta tables

Delta table’s column mapping capability allows for more flexible schema evolution, ensuring that changes in table structure do not disrupt data workflows. With column mapping support in the Lakehouse connector, users can:

Read from an existing delta Lake table with column mapping name/id mode enabled.
Write to existing delta lake table with column mapping name/id mode enabled.
Auto-create table with column mapping name mode enabled when sink table does not exist and source dataset columns contain special chars & whitespaces.
Auto-create table with column mapping name mode enabled when table action is overwriting schema and source dataset columns contain special chars & whitespaces.

These enhancements ensure that data engineers can work with delta tables more efficiently, improving data governance, performance, and maintainability.

Save a new Dataflow Gen2 with CI/CD support from a Dataflow Gen1, Gen2, or Gen2 (CI/CD)

Customers often would like to recreate an existing dataflow as a new dataflow Gen2 (CI/CD), getting all the benefits of the new GIT and CI/CD integration capabilities. Today, to accomplish this, they need to create the new Dataflow Gen2 (CI/CD) item from scratch and copy-paste their existing queries or leverage the Export/Import Power Query template capabilities. This, however, is not only inconvenient due to unnecessary steps, but it also does not carry over additional dataflow settings.

Dataflows in Microsoft Fabric now includes a ‘Save as’ feature in preview, that in a single click lets you save an existing dataflow Gen1, Gen2 or Gen2 (CI/CD) as a new Dataflow Gen2 (CI/CD) item.

Incremental Refresh for Dataflow Gen2

Incremental Refresh for Dataflow Gen2 is now generally available!

Incremental Refresh for Dataflow Gen2 allows you to refresh only the buckets of data that have changed, rather than reloading the entire dataset on every dataflow refresh. This not only saves time but also reduces resource consumption, making your data operations more efficient and cost-effective.

These new capabilities are designed to help you to be successful with your data integration needs and be as efficient as possible. Try it out today in your fabric workspace!

Check ongoing validation status of a Dataflow Gen2 with CI/CD support

When you click Save & run in Dataflow Gen2 with CI/CD support, the process that gets triggered is two-fold:

Validation: it’s a background process where your Dataflow gets validated against a set of rules. If it passes all validations and no errors are returned, then it’ll be successfully saved.
Run: Using the latest published version of the Dataflow, a refresh job gets triggered to run the Dataflow.

If you only wish to trigger the validation process, you only need to click the ‘Save’ button.

What if you want to check the status of the validation? You now have a new entry point in the home tab of the ribbon called Check validation which you can click at any time to give you information of the ongoing validation or the result of a previous validation run.

Be sure to give this a try whenever you want to check the results of a save validation.

OneLake file triggers for pipelines

The Fabric Data Factory team is thrilled to announce that the pipeline trigger experience is now generally available (GA) and now includes access to files in OneLake!

This exciting new improvement to pipeline triggers in Fabric Data Factory means that you can now automatically invoke your pipeline when files or folders have files that arrive, delete, or rename!

We’ve previously supported Azure blob file events in Fabric Data Factory like ADF & Synapse but now that Fabric users are leveraging OneLake as the primary data hub, we’re excited to see the pipeline patterns that you’ll build using OneLake file triggers!

Variable libraries for pipelines

One of the most requested features in Fabric Data Factory has been support for modifying values when deploying workspace changes between environments using Fabric CICD. To accommodate this, ask, we have integrated pipelines into the new Fabric platform feature called Variable Libraries.

With Variable Libraries, you can assign variables to unique values based on different environments, i.e. dev, test, prod. Then when you promote your factory to high environments, you can use different values from the library providing the ability to change values when pipelines are promoted to new environments.

This new preview feature will be super useful not just for CICD but also generically allows you to replace hardcoded values with variables anywhere in your pipelines to achieve the same functionality as global parameters in Azure Data Factory as well.

Spark Job Definition pipeline activity parameter support

The Spark Job Definition (SJD) activity in Data Factory allows you to create connections to your Spark Job Definitions and run them from your data pipeline.

And we are excited to announce that parameterization is now supported in this activity!

You will find this update in the Advanced settings where you can configure your SJD parameters and run your Spark Job Definitions with the parameter values that you set, allowing you to override your SJD artifact configurations.

Azure Databricks jobs activity now supports parameters

Parameterizing data pipelines to support generic reusable pipeline models is extremely common in the big data analytics world. Fabric Data Factory provides end-to-end support for these patterns and is now extending this capability to the Azure Databricks pipeline orchestration activity. Now when you select ‘Jobs’ as the source of your ADB action, you can send parameters to your ADF job allowing maximum flexibility and power of your orchestration jobs.

User data functions in Data pipelines

User Data Functions are now available in preview within Data pipeline’s Functions activity. This new feature is designed to enhance your data processing capabilities by allowing you to create and manage custom functions tailored to your specific needs.

Key highlights

Custom functionality: User Data Functions enable you to define custom logic and calculations that can be reused across multiple Data pipelines. This allows for more flexible and efficient data processing.
Integration in data pipelines: You can add User Data Functions as activities within your Data pipelines. This is done by selecting the Functions activity in the pipeline editor, choosing your User Data Functions as the type, and providing any necessary input parameters.

Check out our documentation to learn more about how to User Data Functions in your data pipelines.

Parameterized connections in Data pipelines

Parameterization of data connections in Data pipelines allows you to specify values for connection placeholders dynamically. This means you can pre-create data connections for various sources, such as Azure Blob Storage, SQL Server or any other data source supported by data pipelines, and reference them through data pipeline’s dynamic expressions at runtime. This feature empowers you to create more flexible and adaptable data pipelines, capable of connecting to different instances of data connections of the same type, such as SQL Server, without altering the pipeline definition.

Key benefits:

Flexibility: Use the same data pipeline definition to dynamically connect to various instances of data connections.
Efficiency: Minimize the need for multiple pipeline definitions, reducing complexity and maintenance effort.
Scalability: Easily manage and scale your data integration processes by leveraging dynamic expressions to handle connection values.

How it works:

During the pipeline run, dynamic expressions within the data pipelines specify values for the connection placeholders, enabling seamless integration with pre-created data connections. This innovation ensures that your data pipelines are not only more efficient but also highly customizable to meet your specific requirements.

We believe this new feature will significantly enhance your data processing capabilities and streamline your workflows. We can’t wait for you to experience the benefits of parameterized connections in your data integration projects.

Table Name parameter support for data destinations

In Dataflow Gen2, you can create parameters, they serve as a way to easily store and manage a value that can be reused throughout your Dataflow.

Major feedback that we’ve heard from our users is the lack of this capability in the Data destination experience for Dataflow Gen2. Thanks to the feedback, we’re now introducing the first support for parameters in the data destination experience where you can set a parameter to be used for the Table name of your destination.

This is available to all destinations that support this field and we’re working on extending this support to other areas of the data destination experience. Try out this new capability and let us know what you think.
