Question 1

How do I handle database schema migrations with Hiberlite?

Accepted Answer

Hiberlite doesn't have built-in migration tools; you need to manually manage schema changes using dropModel() and createModel(), which can lead to data loss if not handled carefully. For incremental updates, you might need to write custom SQL scripts.

Question 2

Is Hiberlite thread-safe for concurrent database access?

Accepted Answer

The README doesn't explicitly mention thread safety, so you should assume caution. SQLite supports limited concurrency, but Hiberlite's bean_ptr and database operations might require external synchronization to avoid race conditions in multi-threaded applications.

Question 3

Can I use raw SQL queries alongside Hiberlite's ORM?

Accepted Answer

Yes, but it's not directly supported in the API; you would need to access the underlying SQLite connection manually. This can break the ORM abstraction and requires careful management to avoid conflicts with Hiberlite's internal state.

Question 4

Hiberlite vs ODB: which C++ ORM is better for SQLite?

Accepted Answer

Hiberlite is lighter and requires no code generation, making it faster to set up for simple projects. ODB, on the other hand, supports multiple databases and has more features like query languages, but it requires a preprocessor and has a steeper learning curve.

Question 5

How to optimize Hiberlite for performance with large datasets?

Accepted Answer

Use lazy loading to fetch objects only when needed, and minimize calls to getAllBeans() for large collections. Consider batching operations or manually tuning SQLite settings, as the ORM layer can add overhead for bulk inserts or complex queries.

Question 6

Does Hiberlite support transactions and rollbacks?

Accepted Answer

Yes, but it's not detailed in the README; you can likely use SQLite's transaction features through the database connection. However, Hiberlite's automatic saving via bean_ptr might complicate rollback scenarios, so manual transaction management is recommended.
