Should Table() be called each request?

[thestephenstanton]

I'm wondering if there is any benefit (or maybe your suggestion) on whether to use A or B and why?

A

type repo struct {
	db *dynamo.DB
}

func (r repo) Get(id int) (something, error) {
	var something something
	err := r.db.Table("somethings").Get("id", id).One(&something)
	if err != nil {
		return something, fmt.Errorf("getting something: %w", err)
	}

	return something, nil
}

B

type repo struct {
	table dynamo.Table
}

func (r repo) Get(id int) (something, error) {
	var something something
	err := r.table.Get("id", id).One(&something)
	if err != nil {
		return something, fmt.Errorf("getting something: %w", err)
	}

	return something, nil
}
