What are the use cases for Django database routers?

Django database routers are used to direct database operations to different databases based on certain criteria. Common use cases include multi-database setups, data partitioning, and read/write splitting.

Can you give me an example of when I would need to use a database router?

Sure! If you have a large application that requires both a primary database for writes and a secondary database for read operations, a router can help direct these operations accordingly.

How do I implement a database router in Django?

To implement a database router, you need to create a class that defines methods like db_for_read, db_for_write, and allow_migrate. Then, you add your router class to the DATABASE_ROUTERS setting in your Django settings file.

Are there any performance considerations I should be aware of?

Yes, using database routers can introduce complexity and potential performance overhead. It's important to test and monitor your application's performance to ensure that the routing logic does not become a bottleneck.
