GreyCat: Efficient what-if analytics for data in motion at scale
作者:
Highlights:
• Existing analytics fail to effectively explore the effects of what-if decisions.
• We combine graphs and time series into multi-dimensional models (Many-Worlds Graphs).
• These are able to update thousands of parallel worlds composed of millions of nodes.
• We benchmark our Many-Worlds Graph open source implementation, called GreyCat.
