Database Sharding

Database sharding is a method of dividing a large database into smaller, more manageable pieces called "shards," which are stored separately. Each shard contains a portion of the data and can be stored on different servers, allowing for faster access, improved performance, and better scalability. This approach helps handle increased user demand efficiently by distributing the load, reducing bottlenecks, and ensuring that no single server becomes overwhelmed. Think of it like splitting a large file into sections so multiple people can work on or access different parts simultaneously, making the system more efficient and resilient.
