What are the best practices for connection pooling with Go SQL driver?
The best practices for connection pooling with the Go SQL driver include setting the maximum number of open connections, configuring the maximum idle connections, and properly handling connection timeouts.
How do I set the maximum number of open connections?
You can set the maximum number of open connections using the SetMaxOpenConns
method on your database connection. For example: db.SetMaxOpenConns(25)
.
What about idle connections?
For idle connections, use the SetMaxIdleConns
method. This helps to maintain a pool of connections that can be reused, improving performance.
Are there any specific timeout settings I should consider?
Yes, you should consider setting connection and read timeouts using SetConnMaxLifetime
and SetConnMaxIdleTime
to ensure connections are not held indefinitely.
