Technical Perspective: Data Distribution For Fast Joins
What is the most drastic way to reduce the cost of communication for parallel data processing algorithms? This is the question studied in "Reasoning on Data Partitioning for Single-Round Multi-Join Evaluation in Massively Parallel…

Reasoning on Data Partitioning For Single-Round Multi-Join Evaluation in Massively Parallel Systems
We introduce a framework for reasoning about data partitioning to detect when we can avoid the data reshuffling step.
