What is the primary purpose of scaling out in NoSQL databases?
Question 10Select one:
To limit data access
To reduce hardware costs
To improve system response time
To increase data complexity
Solution
The primary purpose of scaling out in NoSQL databases is to improve system response time.
Here's why:
-
Scaling out, also known as horizontal scaling, involves adding more machines or nodes to the system to manage increased load.
-
NoSQL databases are designed to expand easily to take advantage of new nodes, which makes them ideal for high-traffic applications.
-
As more nodes are added, the database's ability to handle more traffic improves, which in turn improves the system's response time.
-
This is different from scaling up (or vertical scaling), which involves adding resources such as CPU, RAM, or storage to a single node in the system.
So, the correct answer is "To improve system response time".
