I'm the author of Brewery/Cubes. Both projects are very young - started last year, in December 2010. As for Cubes: goal is to create light-weight framework with pluggable backends. Currently simple SQL backend and MongoDB backend are implemented. Some public projects that are using Cubes for OLAP are: Donations for sport and culture: http://granty.transparency.sk/en/ http://granty.transparency.sk/en/ Public procurements of Slovakia (still under development): http://vestnik-test.democracyfarm.org/en/report/all?cut=date:2011 http://vestnik-test.democracyfarm.org/en/report/all?cut=date... If you are asking about performance, my answer is: I do not know yet, haven't stressed it too much. I would very like to hear any feedback and/or recommendations. Current focus was on simplicity and easy of use, performance will come later. For brewery, here are some blog notes: http://blog.databrewery.org/ http://blog.databrewery.org/ Presentation where data brewery was used in a project: http://slidesha.re/i9O4kC http://slidesha.re/i9O4kC I hope to prepare more information soon, with examples. I want data brewery to be more distributed with cusomisable nodes (like you would be able to use a distant server as a processing node or part of processing stream). Goal of data brewery is to provide "way of working with data streams", focusing more on data analysis than on data transformation. However, it does not mean that you would not be able to use it for the further. Anyway, I would appreciate any feedback, and gladly answer any questions. I am also looking for cooperation, if you are interested, drop me a line. Stefan - @Stiivi on twitter, author of Data Brewery/Cubes
