Graph export in columnar tables

A set of relational tables stored in a columnar format such as Apache ORC, which is particularly suited for scale-out analyses on data lakes and big data processing ecosystems such as the Hadoop environment.

Comments: A full export of the graph dated from January 2019. The export was done in two phases, one of them called "2018-09-25" and the other "2019-01-28". They both refer to the same dataset, but the different formats have various inconsistencies between them.
