What are the differences between in-memory and disk caching?

What are the differences between in-memory and disk caching?

In-memory caching stores data in the RAM for faster access, while disk caching stores data on a hard drive, which is slower.

Can you explain the advantages of in-memory caching?

Sure! In-memory caching offers faster data retrieval, reduced latency, and improved performance for applications.

What about the disadvantages of using in-memory caching?

The main disadvantages include limited storage capacity and data loss if the system crashes, as RAM is volatile.

When should I use disk caching instead?

Disk caching is ideal for large datasets that don't fit in memory or for data that needs to persist across sessions.

Are there any scenarios where both can be used together?

Yes, a common approach is to use in-memory caching for frequently accessed data and disk caching for less frequently accessed data.
