Uber just released an open-source, GPU-based, streaming, in-memory analytical database. This could be a very big deal.
The technology in the BI ecosystem has been re-built over the past 7 years since the advent of the cloud-based MPP database. If Ares or another similar technology got traction it could lead to a fundamental shift in tooling, in user expectations, etc. People have talked about deploying GPUs in analytical databases before, but this is the first and only example of a scale-out deployment to my knowledge.
