Exasol is another MPP database that easily handles super-wide tables, and does all the distribution across nodes for you.

It used to only be available for big enterprises, but now there is a totally free version you can try out: https://www.exasol.com/personal

From what I understand, Exasol is a very fast analytical database for traditional data warehouses. My engine doesn't replace a data warehouse; it solves a type of table that data warehouses simply can't handle: tables with hundreds of thousands or millions of columns with an access model that guarantees interactive response times even in these extreme cases.
