Initialize gocql ips using a constant

Question

I need to initialize gocql with multiple ips, I want to pass the ips from a variable/constant.

How to pass some thing like

gocql.NewCluster(ipvalues)

instead of using

gocql.NewCluster("127.0.0.1", "127.0.0.2")

i want to pass the list of ips through a variable something like an array.

A constant cannot be an array or a slice, but that's actually unrelated to the core of your question. — Jonathan Hall, Aug 23 '18 at 11:01

As you can see, gocql.NewCluser takes a variadic parameter, which means you can pass multiple values separated with commas to the function.

In go, you just need to make your ipvalues variable be a slice of strings and pass it like this:

ipvalues := []string{"127.0.0.1", "127.0.0.2"}

gocql.NewCluster(ipvalues...)

This will have the same effect as writing gocql.NewCluster("127.0.0.1", "127.0.0.2")
