What are the connection pooling parameters in SQLAlchemy?

SQLAlchemy provides several parameters for connection pooling, such as pool_size, max_overflow, and timeout. Would you like to know more about each of these?

Yes, can you explain what pool_size and max_overflow do?

Sure! pool_size defines the number of connections to keep in the pool, while max_overflow allows additional connections beyond the pool size when demand is high.

What happens if I set max_overflow to a very high number?

Setting a high max_overflow can lead to resource exhaustion if too many connections are opened simultaneously, potentially affecting performance.

How do I set these parameters when creating an engine?

You can set these parameters in the create_engine function like this: create_engine('database_url', pool_size=5, max_overflow=10).
