JanusGraph fails on initial startup (cql-es)
Hi all,
I have a problem that's been popping up once in a while regarding only the initial startup of Cassandra/ES/JanusGraph.
Sometimes it fails with "table edgestore doesn't exist", or "table janusgraph_ids doesn't exist". However, if I restart the JG pod, it completes. To me, it sounds like some sort of race condition.
There's a thread for JG 0.6.0 with the same error:
https://lists.lfaidata.foundation/g/janusgraph-users/topic/unconfigured_table_exceptions/85741983?p=,,,20,0,0,0::recentpostdate/sticky,,,20,2,0,85741983,previd=1634849714017760765,nextid=1631631322121685927&previd=1634849714017760765&nextid=1631631322121685927
I'm just surprised it still exists? Is there a good fix (I don't think the thread above gives a consistent solution)?
For reference, I'm using:
janusgraph/janusgraph:1.0.0-20230805-060925.b584085
cassandra:4.0.10
docker.elastic.co/elasticsearch/elasticsearch:7.17.10
To make matters worse, this issue only seem to happen in low-resource hardware. I cannot reproduce locally on my M1 machine, but it happens consistently in a github actions-workflow that spins up a docker-compose with ES, Cassandra and JG.
I can share if interested.

Upgrading from 0.6 to 1.0.0-20230626 caused indexes to disappear
Hi all,
I tried to upgrade from 0.6 to 1.0.0-20230626 yesterday, and I ran into some issues. All of the existing indexes was gone after the upgrade.
My setup is cql-es, using cassandra 3.11.6 and ES 7.16.2. If I recall correctly, the graph used to contain around 10 CompositeIndexes.
Is this a known issue? Should I simply rebuild the indexes?
I've posted the (reduced) output of
mgmt.printSchema() below.
