Isn't MonetDB a columnar store? They did benchmark against MonetDB. Edit: MemSQL too is a columnar store

  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.
    • slagfart 10y ago
      "Incremental Aggregation" is just UPDATE (new value = old value + JOIN value), right? If so, yes :)

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