🆚 PostgreSQL vs. Redis

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.

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.
