Assuming that your column are numeric, you would need 4GB of memory just to store one copy of the object. If this is 5 years, then you would need almost 1GB for a copy, but the processing probably will use up twice as much as it is processing. Try reading a month's worth and see how much you use. In problems like this, you creep up on it; you just try to jump in all at once. Do it in increments and watch the usage.
