Depends on how brave you are :-) We recently had the same need and made https://github.com/netarchivesuite/dvenabler To my knowledge that is the only existing tool for that task an as we are the only ones having used it, robustness is not guaranteed. Warnings aside, it works without problems in our tests as well as the few real corpuses we have tested on. It does use a fairly memory hungry structure during the conversion. If the number of _unique_ values in your grouping field approaches 1b, I loosely guess that you will need 40GB+ of heap. Do read https://github.com/netarchivesuite/dvenabler/issues/14 if you want to try it. - Toke Eskildsen
