What are some effective Redis caching techniques?

Redis offers several caching techniques, including key expiration, data eviction policies, and using hashes for storing related data.

Can you explain key expiration and how it works?

Key expiration allows you to set a time-to-live (TTL) for keys, after which they are automatically deleted from the cache.

What are the different data eviction policies in Redis?

Redis supports several eviction policies like LRU (Least Recently Used), LFU (Least Frequently Used), and allkeys-lru, which determine how keys are removed when memory is full.

How can I use hashes effectively in Redis?

Using hashes in Redis allows you to store multiple fields and values under a single key, which is efficient for related data.
