Question 1

How does Native DB compare to SQLite in Rust?

Accepted Answer

Native DB offers better type safety and automatic migration with Rust types, but SQLite has more mature tooling and supports complex SQL queries, which Native DB lacks. Benchmarks in the README show Native DB is fast, but SQLite has a larger ecosystem.

Question 2

How to set up real-time subscriptions in Native DB?

Accepted Answer

Use the subscription API with filters for insert, update, or delete operations; the documentation provides examples for live updates, but it requires handling transactions and callbacks manually in your code.

Question 3

Is Native DB production-ready for mobile apps?

Accepted Answer

It's designed for multi-platform use, including mobile with Tauri, but the unstable API and active development status mean you should expect breaking changes, so it's better for prototypes or projects with flexible timelines.

Question 4

What serialization libraries work with Native DB?

Accepted Answer

It uses native_model for transparent serialization, supporting libraries like bincode or postcard, and you can implement custom serialization, as mentioned in the features section.

Question 5

How to back up data with hot snapshots?

Accepted Answer

Native DB supports hot snapshots for backup without downtime; refer to the documentation for specific methods, but it's part of the ACID compliance and redb engine integration.

Question 6

Can I use Native DB with async Rust?

Accepted Answer

The README doesn't mention async support; it likely uses synchronous transactions, so for high-concurrency async applications, you might need to wrap it or consider alternatives.
