Multiple vertices generated for the same index value and vertex properties missing with RF3
Hi JG community
We are facing a weird issue with Replication factor 3 with scylla DB as backend.

Re: [Performance Optimization] Optimization around the `system_properties` table interaction
HI @sauverma,
nice, we are truncating the table, too. It's good to have your confirmation that it could safely workaround the issue.
We will analyze the `gc_grace_seconds` setting now.

In scylla grafana board, this issue is seen with high number of foreground read tasks.

Thank you folks for getting back.
@Simone3, yes this issue comes out as read timeout from the shard holding the system_properties table (there is only 1 partition for system_properties

Re: [Performance Optimization] Optimization around the `system_properties` table interaction
Hi Saurabh,
we are experiencing the exact same issue: spark job with one janusgraph instance per partition calling a scylladb cluster. Our symptom is a ton of timeout exceptions due to missing QUORUM

[Performance Optimization] Optimization around the `system_properties` table interaction
Hi all
- The interaction with the underlying KV store via janusgraph client hits the `system_properties` table with a range query where the key is `configuration` (key = 0x636f6e66696775726174696f6e)

Re: Why does JanusGraph use two versions of netty?
Ahh. Actually think I may have answered my own question building from source. Looks like hadoop:2.7.7 and spark-gremlin:3.4.10 are still using netty 3 and the POM just bumped to the latest netty 3

Why does JanusGraph use two versions of netty?
Noticed that there are two versions of Netty in the POM for JanusGraph:
- version 3:https://github.com/JanusGraph/janusgraph/blob/master/pom.xml#L806 &
- version 4:

Re: [janusgraph-foundationdb] - New Release
Sounds like a good thing to do. We should consider updating our documentation (#54) before that, so that users who get started with the new release don't experience any issues regarding installation

[janusgraph-foundationdb] - New Release
Hi all,
I think we should consider doing a release of the janusgraph-foundationdb adapter sometime soon. There have been several changes since the initial 0.1.0 release that warrant a new release.
