Sharding is specific type of database setup where multiple partitions are create many pieces of a database which are used as shards. Sharding help to server hosting and other aspects of database maintenance and it is also contribute to faster query times by diversifying the responsibilities of a database structure. Sharding is a type of database partitioning which is responsible for separates very large databases the into smaller, faster ,and more easily managed parts called data shards. The word shard means a small part of a whole. Sharding is a way to make database systems more scalable, database Sharding has emerged as a kind of horizontal partitioning that can help deal with the problem of slower response times for growing databases. The distribution of database responsibilities across these multiple shards helps engineers to make the most of CPU, memory and resources for a given hardware set.
