About

Memcached is an open source event-based key-value store that keeps data in memory to deliver very low latency access and high throughput.

It can handle over 200,000 operations per second on fast hardware, uses multi-threading to leverage multiple CPU cores, and applies Least Recently Used cache eviction policy when it runs out of memory.

Redis is a popular high-performance in-memory key-value database that persists on disk.

It supports rich data structures beyond simple strings, offers master-replica replication, clustering across up to thousands of nodes via hash-slot sharding, and automatic failover.
