It allows engineers to focus on processing and analytics tasks without worrying about underutilized or overburdened clusters. Additionally, auto-scaling supports high availability and reliability, as workloads can be distributed across nodes dynamically, maintaining performance even under fluctuating demand.

In contrast, option B, Power Query, is primarily a low-code, visual tool for transforming and preparing datasets. While it is valuable for cleaning, shaping, and merging data interactively, it does not manage compute resources or offer automatic scaling. Option C, Synapse Analytics, provides integrated analytics and data warehousing solutions, including big data processing and SQL-based queries. Although it supports performance tuning and workload management, its scaling capabilities are different and do not involve the same dynamic cluster-level auto-scaling that Databricks provides. Option D, Microsoft Purview, focuses on data governance, classification, and policy enforcement and does not manage computational workloads or optimize cost and performance through auto-scaling.

Overall, Azure Databricks stands out as the Microsoft Fabric feature designed to handle large-scale data processing efficiently, automatically adjusting compute resources to optimize performance and reduce costs. This capability is crucial for designing reliable, scalable pipelines and supports a wide variety of analytical and machine learning workloads.
