Nosql Questions
The role of caching in NoSQL databases is to store frequently accessed data in memory, allowing for faster retrieval and improved performance. By keeping frequently accessed data in cache, the database can avoid the need to fetch the data from disk, which is a slower operation. This reduces the overall latency and response time of the database system. Caching also helps in reducing the load on the underlying storage system, as it can serve read requests directly from memory. Overall, caching in NoSQL databases improves performance by providing faster access to frequently accessed data and reducing the need for disk I/O operations.
