 -   To improve performance, [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] computes the aggregate functions `MIN`, `MAX`, `SUM`, `COUNT`, and `AVG` during table scans when the data type uses no more than 8 bytes, and is not of a string type. Aggregate pushdown is supported with or without `GROUP BY` clause for both clustered columnstore indexes and nonclustered columnstore indexes.  
 
--   Predicate pushdown speeds up queries that compare strings of type [v]archar or n[v]archar. This applies to the common comparison operators and includes operators such as `LIKE` that use bitmap filters. This works with all collations that SQL Server supports.
