MongoDB的5个最佳替代品
PostgreSQL
PostgreSQL is the world's most advanced open-source relational database. Known for its reliability, feature richness, and SQL compliance, it supports both relational and JSON data with strong ACID guarantees.
✅ 장점
- • Full ACID compliance with robust transactions
- • Advanced SQL features (CTEs, window functions, etc.)
- • Supports both relational and JSON data (JSONB)
❌ Cons
- • Vertical scaling primarily (horizontal is complex)
- • More rigid schema requirements
- • Can be slower for simple read-heavy workloads
Airtable
Airtable is a flexible database platform that looks like a spreadsheet but acts like a database. Perfect for organizing anything from content calendars to inventory.
✅ 장점
- • Powerful relational databases
- • Multiple views (Grid, Kanban, Calendar)
- • Strong automation
❌ Cons
- • Limited free tier records
- • Can be expensive at scale
- • Not for long-form content
Notion
Notion is an all-in-one workspace for notes, docs, wikis, and databases. Known for flexibility and combining many tools into one.
✅ 장점
- • All-in-one workspace
- • Great for docs + databases
- • Flexible page structure
❌ Cons
- • Databases less powerful than Airtable
- • Can be slow
- • Limited automation
Redis
Redis is an open-source, in-memory data structure store used as a database, cache, message broker, and streaming engine. It supports rich data structures beyond simple key-value pairs.
✅ 장점
- • Rich data structures (lists, sets, sorted sets, hashes)
- • Built-in persistence options (RDB, AOF)
- • Pub/Sub messaging support
❌ Cons
- • Higher memory usage than Memcached
- • Single-threaded for commands (I/O is multi-threaded since v6)
- • Licensing changes with Redis Ltd
Memcached
Memcached is a high-performance, distributed memory object caching system designed for speeding up dynamic web applications by alleviating database load. It's simple, fast, and battle-tested.
✅ 장점
- • Extremely simple and lightweight
- • Multi-threaded architecture
- • Lower memory overhead per key
❌ Cons
- • Only supports simple key-value strings
- • No built-in persistence
- • No pub/sub or messaging
