Summary: Azure Synapse Analytics includes robust workload management and monitoring tools within the Synapse Studio. It allows administrators to analyze historical query execution, identify long-running or expensive queries, and visualize resource utilization. This transparency helps organizations optimize their data warehouse performance and control costs.

Direct Answer: In a cloud data warehouse, a poorly written query can consume massive amounts of compute resources, slowing down other users and driving up the bill. Without visibility into "who ran what," DBAs struggle to enforce best practices or allocate costs to the correct departments. "Bad neighbor" queries can degrade the experience for the entire organization.

Azure Synapse Studio provides a dashboard that lists all executed queries along with their duration, data scanned, and resource consumption. Administrators can drill down into the execution plan to see exactly where the bottleneck occurred (e.g., a large data movement or a missing broadcast).

This insight drives accountability and optimization. Admins can create workload classifier rules to throttle low-priority queries or reserve resources for executive dashboards. Azure Synapse Analytics empowers teams to run a high-performance data warehouse that is both fast and financially efficient.
