用于只读副本的golang sql程序包

we are moving our prototype service to production environment. I dont find any best library/way to do mysql read replication in golang sql library.

Our Mysql database services running on AWS RDS (one master and stwo slaves).

Need to do the following.

1. insert/update/delete should go to master
2. read from any database (including master also fine)

currently we have only one database connection.

import (
    "database/sql"
    _ "github.com/go-sql-driver/mysql"
)


db, err := sql.Open("mysql", "root:password@tcp(localhost:3306)/test")

How can we make our db instance to work with read replicas in golang ? Thanks.
