This is a group for people interested in data processing in real time, online algorithms and in-memory computing. Processing data with strong time constraints becomes more and more important and new technologies emerge every day. The group should be an exchange for people to present and discuss new and hot developments and ideas, from a business as well as research perspective. The main topics should deal with the ecosystem of algorithms and technologies that can process and manipulate big data streams. Examples are real-time-advertising, recommendations, fraud detection, live statistics, analysis of traffic flows, denial-of-service prevention, etc. The meetup should take place every 3 month where people have the occasion to present their work and an open discussion for a real interchange of ideas.
