NoSQL scales horizontally by design. Frame the concept in practical terms so you can explain it during interview discussion.
NoSQL databases like MongoDB are designed to scale out by adding more servers, making them well-suited for large-scale, distributed systems. In a social media platform, for instance, this allows the service to handle a growing user base by distributing the data across many servers, enhancing performance and availability.
Additional Notes
How does NoSQL handle scalability differently than SQL?
