What are the main challenges of distributed caching?

The main challenges include data consistency, cache invalidation, network latency, and handling cache misses.

Can you explain data consistency in more detail?

Data consistency ensures that all nodes in the cache reflect the same data. In distributed systems, achieving this can be complex due to concurrent updates.

What strategies can be used for cache invalidation?

Common strategies include time-based expiration, manual invalidation, and using a publish-subscribe model to notify nodes of changes.

How does network latency affect distributed caching?

Network latency can slow down data retrieval from the cache, impacting application performance. Optimizing network paths and using local caches can help.

Are there any tools that can help manage distributed caching?

Yes, tools like Redis, Memcached, and Apache Ignite are popular for managing distributed caching effectively.
