* Bistro Engine: https://github.com/asavinov/bistro/blob/master/core - a general-purpose column-oriented data processing engine which radically changes the way data is being processed

* Bistro Streams: https://github.com/asavinov/bistro/blob/master/server - a light-weight library for stream analytics
