Re: [Performance Issue] Large partitions formed on janusgraph_ids table leading to read perf issues (throughput reduces to 1/3rd of original)
In scylla grafana board, this issue is seen with high number of foreground read tasks.

Re: [Performance Optimization] Optimization around the `system_properties` table interaction
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

[Performance Issue] Large partitions formed on janusgraph_ids table leading to read perf issues (throughput reduces to 1/3rd of original)
Hi all
We are using janusgraph at zeotap at humongous scale (~70B V and 50B E) backed by scylla.
Right now I am facing an issue in janusgraph_ids table, wherein there are large partitions created in

[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.

Re: [DISCUSS] Monthly Video Calls/Office Hours
I think it would be just okay to have a monthly repeating meeting.
Do we also want to use a google document to keep notes?

As we are now under LF AI & Data, we can ask for Zoom account for regular JanusGraph meetings.

Option for "reply to sender" is too prominent
Hi Marc,
It definitely makes sense to prioritize "Group Reply".
I requested John Mertic to change the default option to `Group Reply`.
I'm also voting +1 to remove the option `Reply to Sender`.

The new mailing list stimulates users to use the option "reply to sender". This means that discussions between OP and expert become invisible to other users. It also means that experts cannot answer
