Awesome thank you all for the great info and recent presentations!  We are prototyping bulk export + deserialize from Cloud Bigtable over approx. the next week and will try to report back if we can produce something useful to share.  Thanks again, -Elliot

At zeotap we ve taken the same route to enable olap consumers via apache spark. We presented it in the recent janusgraph meet-up at https://lists.lfaidata.foundation/g/janusgraph-users/topic/janusgraph_meetup_4/82939376. We are using ScyllaDB as the backend.

If you look back at this week's OLAP presentations (https://lists.lfaidata.foundation/g/janusgraph-users/topic/janusgraph_meetup_4/82939376) you will see that one of the presenters exactly did what you propose: they exported rows from scylladb and converted it to gryo format for import into TinkerPop HadoopGraph. You might want to contact them to coordinate a possible contribution to the JanusGraph project.
