What are the differences between memory caching and disk caching?

What are the differences between memory caching and disk caching?

Memory caching stores data in RAM for quick access, while disk caching uses slower disk storage. Memory is faster but volatile.

When should I use memory caching over disk caching?

Use memory caching for frequently accessed data that requires fast retrieval, like session data. Disk caching is better for larger datasets.

What are the performance implications of each?

Memory caching offers lower latency and higher throughput, while disk caching can lead to higher latency but is more cost-effective for large data.

Can I combine both caching methods?

Yes, combining both can optimize performance by using memory caching for speed and disk caching for larger, less frequently accessed data.
