#DATABASE SHARDING POSTGRESQL SOFTWARE#

Vertical partitioning assigns different columns within a table to different servers, but this technique is not widely used. Vertical partitioning and horizontal partitioning are two different methods of partitioning tables into shards. More often, the rows in a single table are divided between the shards. In a simple implementation, the individual tables can be assigned to different shards. The database can be divided into shards based on different methods. Each section is a shard, and is stored on a different server. Database sharding divides the table records in a database into smaller portions. Horizontal scaling, which is also known as “scaling out”, adds additional servers to distribute the workload.ĭata sharding is a common way of implementing horizontal scaling. This allows it to store more data and process a query more quickly and effectively. Vertical scaling involves upgrading the server hosting the database with more RAM, CPU ability, or disk space. What is Database Sharding?Īs databases grow larger, they can be scaled in one of two ways. It also describes some of the main sharding strategies and provides some database sharding examples. This guide explains how database sharding works and discusses some of the advantages and disadvantages of sharding. A sharded database distributes the records in a database’s tables across different databases on different computer systems. One popular solution to this problem is database sharding.

As the database grows, it becomes more time-and-storage intensive to store the data.

Many software applications use a relational database management system (RDBMS) to store data.
