Sharding
MongoDB supports horizontal scaling through sharding, which involves the distribution of data across multiple servers, divided into smaller pieces known as shards. Sharding plays an essential role in managing and organizing large-scale data.
Moreover, sharding allows for the creation of distributed databases to support geographically distributed applications, enabling policies that enforce data residency within specific regions.
Why do you need sharding?
Imagine your application’s data is growing rapidly and starting to push the limits of your database. As data volume increases, you may encounter a range of issues, the most immediate being degraded performance. Queries that once returned results quickly may now take noticeably longer, slowing down your application and frustrating users with laggy or delayed responses.
Storage is another critical concern. Every system has practical limits on how much data it can store and manage efficiently. If your...
