One billion rows


The One Billion Row Challenge is devised for Java, but this is very much q territory. A billion-row query? Not a problem. And the challenge provides a showcase for non-Java solutions.

The “naive” Java solution looks verbose and cumbersome to a qbist eye. The key questions for qbists:

  1. Does a naive q solution scale implicitly and efficiently to a billion rows, or does one have to partition the problem?
  2. Can a naive solution be sped up with extra logic?
