[Redis] SCAN Pattern

scan.go

var (
    cursor int64
    items []string
)

results := make([]string, 0)

for {
    values, err := redis.Values(conn.Do("SSCAN", key, cursor))
    if err != nil {
        return
    }

    values, err = redis.Scan(values, &cursor, &items)
    if err != nil {
        return
    }

    results = append(results, items)

    if cursor == 0 {
        break
    }
}
