 SHARDING Sharding  is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations. Database systems with large data sets or high throughput applications can challenge the capacity of a single server. For example, high query rates can exhaust the CPU capacity of the server. Working set sizes larger than the system’s RAM to stress the I/O capacity of disk drives. There are two methods for addressing system growth:  Vertical scaling. Horizontal scaling. Vertical Scaling  involves increasing the capacity of a single server, such as using a more powerful CPU, adding more RAM, or increasing the amount of storage space. Limitations in available technology may restrict a single machine from being sufficiently powerful for a given workload. Horizontal Scaling  involves dividing the system dataset and load over multiple servers, adding additional ...
