What is sharding in NoSQL databases and how does it improve scalability?

Sharding in NoSQL databases refers to the process of horizontally partitioning data across multiple servers or nodes. Each shard contains a subset of the data, and together they form the complete dataset.

Sharding improves scalability in NoSQL databases by distributing the data and workload across multiple servers. This allows for parallel processing and increased storage capacity, as each shard can be stored on a separate server. By distributing the data, the overall system can handle larger amounts of data and higher traffic loads, resulting in improved performance and scalability. Additionally, sharding enables the system to easily add more servers as the data grows, ensuring that the database can handle increasing demands without sacrificing performance.
