🆚 Memcached vs. PostgreSQL

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.

PostgreSQL, also known as Postgres, is a powerful open-source object-relational database system that extends SQL with features for storing structured, semi-structured and geometric data.

It supports ACID transactions, multiversion concurrency control (MVCC), advanced indexing types (GiST, GIN, BRIN), native JSON/JSONB with indexing, extensibility through custom types and functions, full-text search, foreign data wrappers, and geospatial queries via PostGIS.
