On the other hand, SQL servers still have

When increased performance is essential for larger databases and you've maxed out your stored procedures, and your hardware has been upgraded as well, you'll need to distribute the work across multiple servers. This is where partitioning and sharding come into play.

Although both sharding and partitioning essentially involve dividing a large set of data into smaller subsets, sharding involves spreading the data across multiple computers, while partitioning does not.

Starting with version 10.0, PostgreSQL supports declarative partitioning: range, list, or hash partitioning.

MS SQL Server supports horizontal partitioning: dividing hong kong whatsapp number data a table with many rows into multiple tables with fewer rows.

MS SQL Server also supports partitioning through federation. “Federated partitioned views” are views in which tables are spread across different servers to balance the processing load.

To retrieve the logs from the servers, certain commands are needed. These commands are called distributed partitioned views. They use typical SQL statements, along with the UNION keyword, to extract the data from all the distributed servers.

DML statements (INSERT, UPDATE, and DELETE) can also be used when specific rules are observed in the underlying tables. Also, note that federated partitioned views are only supported in enterprise editions.

Although federated partitioned views can be implemented in any other edition, since there is no distinct syntax for them, they will not be recognized as federated partitioned views. The rules to recognize the view as partitioned across servers are only available with enterprise editions.

Using this partitioning technique typically increases performance by 20% to 30% in most applications, making it a very useful tool if your company manages a lot of data.

Replication
While partitioning involves dividing the database into smaller subsets and distributing the partitioned tables across different nodes, replication involves copying the database across multiple databases to provide fast lookup and faster response time.
