Quick Comparison
| Database | Pros | Cons | Best For |
|---|---|---|---|
| SQLite | Zero-setup, file-based, great for small bots | Limited concurrency, single-node | Hobby, prototypes, low traffic |
| Postgres | Strong consistency, relations, indexing | Requires managed hosting or ops | Production bots, analytics |
| MongoDB | Flexible schema, fast iteration | Schema drift risk, consistency trade-offs | Content-heavy/doc-centric data |
Recommendations
- Start with SQLite for quick MVPs and tests
- Move to Postgres when multi-guild data and relations grow
- Choose Mongo for document-heavy, flexible content
