Upgrading from 0.6 to 1.0.0-20230626 caused indexes to disappear
@rydbirkjr What were the upgrade steps you took? Was it just docker image bump up?

@Florian Hockmann the deletion process is not documented well, could you share your cronjob query to delete particular vertex or edge?

Janusgraph with bigtable with olap+oltp
In OLAP, you can setup a spark cluster, allowing you to transforme your gremlin traversal on spark stuff.Do you have any such examples where spark cluster could be used with bigtable as a backend for OLAP queries?

Janusgraph with bigtable with olap+oltp
thanks let me check these out. BTW I understand that janusgrpah has OLAP capabilities, but I was curiuos if both solutions could work hand in hand. like transaction logs from oltp is passed down to olap solution, so that we don't have to do double raw data processing for ingestion into graph.

Periodic Data deletion in Janusgraph
thanks @florianhockmann . Just curious why did you use the mixed index? is it because of running range queries on node creation/event timestamp. Also given number of nodes / edges to be deleted could be very large. Did you use some kind of batching or single query to delete everything? and how did it impact read write on the instance?
