You have a Microsoft Azure SQL data warehouse to which 1,000 Data Warehouse Units (DWUs) are allocated. You plan to load 10 million rows of data to the data warehouse. You need to load the data in the least amount of time possible. The solution must ensure that queries against the new data execute as quickly as possible. What should you use to optimize the data load?
Correct Answer: A
Explanation/Reference: Explanation: Resource classes are pre-determined resource limits that govern query execution. SQL Data Warehouse limits the compute resources for each query according to resource class. Resource classes help you manage the overall performance of your data warehouse workload.Using resource classes effectively helps you manage your workload by setting limits on the number of queries that run concurrently and the compute-resources assigned to each query. Smaller resource classes use less compute resources but enable greater overall query concurrency Larger resource classes provide more compute resources but restrict the query concurrency References: https://docs.microsoft.com/en-us/azure/sql-data-warehouse/resource-classes-for-workload- management
