I stand corrected! Edit: However, the reference states "At this time (May 2016), there aren't any available open-source and free systems that have all the features listed above". Greenplum does actually implement all of these features, and is open source. I guess I just take issue with all the hyperbole in use.

You managed to check all of their docs already? Because as far as I know greenplum doesn't have incremental aggregation.

    Yeah... do you have ANY experience with column stores?
