🆚 Couchbase vs. Memcached

Couchbase is a distributed NoSQL database that was created in 2011 as a fork of CouchDB and designed for high-performance, scalable applications using JSON data.

It combines a document store with key-value access, supports SQL++ queries with joins and ACID transactions, includes built-in services for full-text search, analytics, and event processing, and uses a memory-first architecture with managed caching, clustering, and cross data center replication for low-latency operations and high availability.

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.
