Table patriating rules You cannot change the data type of the partitioning column once the table is partitioned. You can move an index to a partition scheme after it has been created. You cannot use the SWITCH option of ALTER TABLE statement on replicated tables. For a unique key or primary key index to be partitioned, the partitioning key must be part of the unique key (or the index key). Partitioning key of an index doesn’t have to be part of the index key. For More information check this Link What is the Difference Partitioning Type on SQL SERVER We have two kind of partitioning in SQL Server Vertical Partitioning and Horizontal Partitioning let’s go deeply to know what is the difference between the two types For more Information about Horizontal Partitioning, Vertical Partitioning and Hardware Partitioning go for this Link Vertical Partitioning Vertical partitioning segments columns into multiple tables containing the same rows Vertical partitioning divides a table into multiple tables that contain fewer columns. Vertical Partitioning The two types of vertical partitioning are normalization and row splitting: by removing some columns from the primary table to Secondary table that are linked to the primary table by primary key and foreign key relationships. We cannot decide vertical partitioning is good or bad from the performance because it’s based on x of reasons (Column Data Type, Column Size, and Volume of data …) so it’s ultimately not good not bad. As we can see from the image based on our requirement and our Queries hitting this table we can diced how we can splitting the Table by this way we will reduce the IO and CPU for the query scan When I can use Vertical Partitioning: If I had 100 columns (or some large number) and didn’t often query some of them, or queried others very often, then I can save I/O and unneeded reads by moving some data to another table. Like the Example on the image Horizontal Partitioning Horizontal partitioning divides a table into multiple tables. Each table have the same columns (Same table structure but the data distributed in this multiple tables according the igure2 Rang partition so if we have Millions
