Query for JANUSGRAPH_RELATION_DELIMITER
JVM instance is only one, which is running multiple instances of Janusgraph, that is why i am facing this issue.
If I provide the delimiter env varibale, it will be applied to all the instances which i do not want

Best configuration for a single server
@Florian Hockmann Do you use the same janusgraph servers to write the data as well or these servers are only reposible for reading the data? I want to understand if keeping Janusgraph as servers has any performance improvements in writing data. Currently we use embedded janusgraph which fails with many exceptions due to memory and performance.
What do you recommend based on your experience?

Java 17 support
Does that mean I can use Janusgraph as a dependency with a spring boot application running over java 17?

Different vertex Ids with exactly same properties
So, I noticed that I have set read-consistency-level as ONE and write-consistency-level as QUORUM,
I doubt this can give opportunity for race condition, where some cassandra nodes has yet to be completed the write operation for a particular record but another service pod has read for the same record ID and thinks that the record does not exist.

StaleIndexRecordUtil.forceRemoveVertexFromGraphIndex not working
I can go ahead with .drop().iterate() method,
But the issue is, in past I have seen that, even though I drop such vertices with drop(), somehow they come back into existence after some time (when I say 'come back' I literally mean with same vertex ID).
Which is why I doubt the correctness of using drop.
In case if I can get the mapping of vertex ID and the property value, I may be able to find some workaround 🙂

StaleIndexRecordUtil.forceRemoveVertexFromGraphIndex not working
requires values of all properties of that vertex which are used for each composite indexThis could be difficult for me to identify! Is there any way to read graphindex and janusgaph_ids table to identiy which vertex id is mapped to which properties?

StaleIndexRecordUtil.forceRemoveVertexFromGraphIndex not working
One more observation which I would like to add is:
Sometimes,
g.V().has('fileId', '1234') returns a vertex, but surprisingly the if I do a valueMap on it, it returns empty result []
The way my service works, I wont be able to reindex it in this form.
So something is probably wrong with indexes only is what I assume!16 replies
