- Sharding is the concept of splitting a particular data to distribute it among various databases.
- The process is highly beneficial as it can make the data manageable and improve performance.
- Blockchain developers are looking to adopt the technique for the purpose of dealing with their latency and scalability issues.
What is the Sharding Process?
An important concept in the Database Management System (DBMS) is the process of “Sharding” also known as, “database sharding”. The process of sharding is crucial to distribute and storing datasets among various resources.
A shard, in its simplest form, means a ‘small fraction’ of any bigger data. A ‘database shard’ is a horizontal distribution of a dataset across many databases. These shards are easily manageable and can be stored across multiple servers.
What is the Need for Sharding?
The process of database sharding allows the database management process to be smoother. Shards are scalable architectures, easier to manage, and faster to analyze and access. They help enhance database scalability and management. The performance is also enhanced by reducing the load on one single server.
The need for a sharding process arises while dealing with enormous datasets. The data that is homogenous in nature and is larger in volume is suitable for sharding. The distribution of data is done based on a single criterion. Sharding, not only makes data more manageable, but it also reduces the transaction costs by a significant amount.
How Does it Work?
Through the process of sharding, the data is divided into multiple databases using preset criteria. For example, a dataset might be distributed based on different factors such as age, gender, nationality, grade, and so on. The partitioned datasets are then distributed across various servers. Each one of these servers or nodes, stores and process the subsets. All shards are processed on varied servers but possess the same design.

Implementations of Sharding
Sharding is adopted by various data management systems including MongoDB, MYSQL, MYSQL Cluster, and Oracle Database. It is also implemented in distributed file systems such as Apache Hadoop, Google File Systems, ElasticSearch, Hibernate Shards, and so on.
Role of Sharding in Blockchain Management
The sharding technique is being used by blockchain technology developers. Scalability remains a challenge for many blockchain companies. The sharding process can be helpful in enhancing transaction speed and managing complex data more efficiently for the purpose of tackling scalability issues.
Ethereum, a decentralized software platform, is at the forefront of testing sharding, as one of the processes that can provide solutions to scalability issues. The sharding process can result in lower transaction costs and improved performance of the platform. Cross-shard attacks possess serious threats to the network and are a challenge to overcome. While sharding remains in the research stage, it is still one of the top priorities for the firm as its adoption can benefit the company greatly.
Future Prospects for Sharding
Sharding plays a significant role in Database Management Systems and has the potential to transform other businesses like blockchain management. While the threat of hacking remains a challenge to the industry, the system will need a solution to tackle this problem and adopt the technique. Sharding can largely provide solutions to latency issues.
