- ✓Built-in horizontal scaling with sharding
- ✓Great for rapidly evolving, denormalized data
🐘PostgreSQL
- ✓Strong relational integrity and ACID guarantees
- ✓Powerful SQL with joins and complex queries
- ✓JSONB gives document flexibility when needed
- ✓Mature, predictable behavior at scale
Verdict
Pick MongoDB for flexible, document-shaped data and easy horizontal scaling. Pick PostgreSQL for relational integrity and complex querying — with JSONB as a bonus.
Frequently asked
Is MongoDB faster than Postgres?+
It depends on the workload; MongoDB suits document reads, Postgres excels at relational queries.
Can Postgres store documents?+
Yes — PostgreSQL's JSONB type handles document data with indexing and querying.
Which is better for scaling?+
MongoDB sharding is built-in; Postgres scales well but horizontal scaling needs more setup.
