A Google search reveals this paper: https://arxiv.org/abs/1506.02226 https://arxiv.org/abs/1506.02226 This paper claims a "97x improvement" over traditional (non-parallelized) DBSCAN algorithms, but that's not a very helpful claim, because it does not indicate what the computational costs are as a function of, say, the number of data points or dimensions.
