Abstract
Abstract
Microsoft SQL Server can use two physical operators to aggregate data – the hash and the stream aggregation.
In the session, you will see the differences in terms of the internal algorithm, performance, scalability, hardware consumption and understand the limitations of these operators.
In the end of the session you also learned how to implement the right index strategy to boost the query execution for aggregations.
