How do Redis and Memcached compare for caching?
Redis and Memcached are both in-memory data stores, but they have different features. Redis supports data structures like strings, hashes, and lists, while Memcached is primarily a key-value store.
What are the performance differences between them?
Redis generally offers better performance for complex data types and operations, while Memcached is faster for simple key-value lookups due to its simplicity.
Which one should I use for a web application?
It depends on your needs. If you require advanced data structures and persistence, go with Redis. For simple caching, Memcached might be sufficient.
Can you explain the persistence features of Redis?
Redis offers persistence through RDB snapshots and AOF (Append Only File) logging, allowing you to recover data after a restart.
