Types

type GroupOpSpec 

type GroupOpSpec struct {
	Mode    string   `json:"mode"`
	Columns []string `json:"columns"`
}

GroupOpSpec in package experimental defines a special group() function that has just one mode called "extend", which adds additional columns to the group key. This is a workaround until schema introspection is implemented:
