+When working with large datasets, you may often need to compute the sum of values for the top N groups and aggregate the remainder separately. This article demonstrates several methods to achieve that in ClickHouse.
+
+Dataset Setup
+We'll start by creating a table top_with_rest and inserting data for demonstration purposes:

+These methods offer different approaches for handling the Top N rows and aggregating the remainder in ClickHouse. Depending on your requirements—whether you prefer using UNION ALL, arrays, window functions, or totals—each method provides flexibility for efficient querying.
