What is the difference between horizontal and vertical scaling in NoSQL databases?

Horizontal scaling in NoSQL databases refers to the process of adding more machines or nodes to distribute the data across multiple servers. This allows for increased storage capacity and improved performance as the workload is divided among multiple machines.

On the other hand, vertical scaling in NoSQL databases involves increasing the resources (such as CPU, RAM, or storage) of a single machine or node. This approach allows for handling larger amounts of data or increased processing power on a single server.

In summary, horizontal scaling focuses on adding more machines to distribute the workload, while vertical scaling involves increasing the resources of a single machine to handle more data or processing power.
