What are the best practices for connection pooling in Go?

Connection pooling in Go is essential for optimizing database interactions. Key practices include setting a maximum number of connections, using a connection pool library, and properly handling connection timeouts.

How do I set the maximum number of connections?

You can set the maximum number of connections using the SetMaxOpenConns method on your database connection. For example: db.SetMaxOpenConns(25).

What library do you recommend for connection pooling?

I recommend using the database/sql package, which provides built-in support for connection pooling. You can also consider third-party libraries like pgx for PostgreSQL.

How can I handle connection timeouts effectively?

To handle connection timeouts, you can set the SetConnMaxLifetime method to define how long a connection can be reused. Additionally, use context with deadlines for queries to avoid hanging connections.
