What is the difference between partition by and group by?
PARTITION BY gives aggregated columns with each record in the specified table. A GROUP BY normally reduces the number of rows returned by rolling them up and calculating averages or sums for each row. PARTITION BY does not affect the number of rows returned, but it changes how a window function’s result is calculated.
Does SQL Server support sharding?
Horizontal partitioning can be done both within a single server and across multiple servers, the latter often being referred to as sharding. In SQL Server 2005, Microsoft added the ability to create up to 1,000 partitions per table.
