What are the different caching techniques and how do they compare?

There are several caching techniques, including in-memory caching, disk caching, and distributed caching. In-memory caching stores data in RAM for fast access, while disk caching uses storage devices. Distributed caching spreads data across multiple servers for scalability. Would you like to know more about a specific technique?

Can you explain in-memory caching in more detail?

In-memory caching stores frequently accessed data in the server's RAM, which allows for extremely fast retrieval times. It's ideal for applications that require quick access to data, like web applications. However, it can be limited by the amount of available memory and may not persist data after a server restart.

What are the pros and cons of using disk caching?

Disk caching uses storage devices to cache data, which allows for larger data sets compared to in-memory caching. The main advantage is persistence; data remains available even after a restart. However, access times are slower than in-memory caching, which can impact performance.

How does distributed caching work?

Distributed caching involves multiple servers working together to cache data. This technique improves scalability and fault tolerance, as data is spread across different nodes. If one server fails, others can still provide access to the cached data. It's commonly used in large-scale applications.
