What are the differences between SQLAlchemy connection pooling and direct connection?

What are the differences between SQLAlchemy connection pooling and direct connection?

SQLAlchemy connection pooling allows multiple database connections to be reused, improving performance. Direct connection creates a new connection for each request, which can be slower.

When should I use connection pooling?

You should use connection pooling when your application requires frequent database access, as it reduces the overhead of establishing new connections.

Are there any downsides to using connection pooling?

Yes, connection pooling can lead to resource exhaustion if not managed properly, and it may introduce complexity in connection management.

How do I implement connection pooling in SQLAlchemy?

You can implement connection pooling in SQLAlchemy by using the create_engine function with the pool_size and max_overflow parameters.
