Hi! please note that there's a proposal under discussion that may provide a new place for the Apache MADlib community to apply their efforts: https://lists.apache.org/thread/1f8jwpjnn430bhsjq98qxlgjojpqrfdh
While the current state of the MADlib community is a bit dwindling we hope that the next generation codebase coupled with active user community will provide a much needed boost. IOW, while the initial idea for the Apache MADlib was to be a standalone community (serving ALL PostgreSQL derived projects) perhaps a better idea is to exist under the umbrella of the CloudBerry host project. At any rate -- please let us know what do you all think in that Incubator thread. Thanks, Roman.
