Hadoop’s value—being able to crunch large datasets—often paled in comparison to its costs. Doubly so as hardware improved, eating away at the lower end of Hadoop-worthy work. Google goes a step further in offering compute instances with its specialized TPU hardware. The elephant was unstoppable. Until it wasn’t.

The division by a power of two ( / (2 N )) can be implemented as a right shift if we are working with unsigned integers, which compiles to single instruction: that is possible because the underlying hardware uses a base 2.
