Demystifying Spark Profile Optimizations in Microsoft Fabric | FABCON Europe Vienna 2025

Optimizing Spark workloads in Microsoft Fabric can be a complex endeavor, given the array of available configurations and techniques. Terms like V-Order, Z-Order, and considerations for read-heavy versus write-heavy profiles often add to the confusion.

In this session, we’ll bring clarity to these concepts, offering a structured overview of each optimization strategy.

Through practical examples and performance considerations, attendees will gain insights into selecting the appropriate configurations for their specific use cases, whether dealing with read-intensive analytics or write-heavy data ingestion processes.

By the end of this talk, you’ll be equipped with the knowledge to make informed decisions, turning the complexity of Spark optimizations into a strategic advantage
