🆚 Memcached vs. MongoDB

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.

MongoDB is a NoSQL, collection-oriented, schema-free document database that supports deployment across cloud or on-premises.

It stores documents in BSON (JSON-like) format, offers ACID multi-document transactions, powerful indexing (including geospatial and text), horizontal scalability via sharding, and high availability through replica sets.
