A Standard E64pds v6 costs: $3.744 / hr on demand. At 63 nodes - the cost is: $235.872 / hr - still cheaper than a Snowflake 4XL cluster - costing: 128 credits / hr at $3/credit = $384 / hr.
At 5 seconds - the query technically cost: $0.3276
That's like calculating a trip cost based on gas cost without accounting for car rental, gas station food, and especially mandatory bathroom fee after said food.
If I used "spot" instances - it would have been 63 x $0.732/hr for a total of: $45.99 / hr.
