WebbDatabase sharding is a type of horizontal partitioning that splits large databases into smaller components, which are faster and easier to manage. A shard is an individual partition that exists on separate database server instance to spread load.

Horizontal partitioning is a database design principle whereby rows of a database table are held separately, rather than being split into columns (which is what normalization and vertical partitioning do, to differing extents). Each partition forms part of a shard, which may in turn be located on a separate database server or physical location. There are numerous advantages to the horizontal partitioning approach. Since the tables are divi…
