Which of the following is a limitation of USQL regarding the number of bucketed results?

The correct answer reflects the limitation of USQL regarding the number of bucketed results that can be returned in a query. USQL has a default limit of 10,000 results, which means that when you run a query, only up to 10,000 results will be returned unless this limit is explicitly adjusted in the query parameters. This restriction is important for performance reasons, as it helps manage and optimize resource usage in processing and retrieving data from large datasets.

Understanding this limit helps users design their queries more effectively. If you expect to handle more than 10,000 results, you must account for that in your query setup by using pagination or modifying the query to reduce the result set. Being aware of these constraints is vital for successfully working with USQL in a way that aligns with both the capabilities and performance considerations of the system.
