custom vertex id (String) feature to avoid duplicate vertex
Thanks for quick response @porunov here regarding LIST.
Can you suggest any workaround for following issue mentioned -
But due to this we are facing a ton of PermanentLockingException(Expected value mismatch for X: expected=Y vs actual=Z). We have retry(5) transaction in place with exponential back off(5ec), but still we are face this issue a lot. What else can be done here ?

In our case, we have optimistic locking enabled on recordId, for instance -
JanusGraphManagement mgmt = graph.openManagement();
mgmt.makePropertyKey("recordId").dataType(String.class).make() : mgmt.getPropertyKey("recordId");
JanusGraphIndex recordIdIndex = mgmt.buildIndex("recordIdIndex", Vertex.class).addKey(recordId).unique().buildCompositeIndex();
mgmt.setConsistency(recordId, ConsistencyModifier.LOCK);
mgmt.setConsistency(recordIdIndex, ConsistencyModifier.LOCK);
But due to this we are facing a ton of PermanentLockingException(Expected value mismatch for X: expected=Y vs actual=Z).
We have retry(5) transaction in place with exponential back off(5ec), but still we are face this issue a lot.
What else can be done here ?
In our case, currently we do not have property LIST used, and only have property string. for instance - property(Constants.RECORD_ID, recordId) and property(Constants.TYPE, type).
So above issue that you explained is only for LIST ?

Best configuration for a single server
@Florian Hockmann Did you face similar issue at your end when you had remote setup used while creating vertices and edges. https://discord.com/channels/981533699378135051/1272925642832478228/1272925642832478228

How does remote gremlin server reacts to credential rotation.
If I understand you correctly, what your suggesting is to have 2 passwords active at given point of time and perform gremlin deployment restart, so that new password can be picked up by server.

TraversalOpProcessor Cache
One more question - I have a remote gremlin setup. From my java application when I query the gremlin server, in first query returns me response in 60 sec. If execute same query within 30 sec I get response within 10 sec. But if I send query after 30sec-1min I get response again in 60 sec. Any clue why so ?

TraversalOpProcessor Cache
When we say script here - we are stating about - "org.apache.tinkerpop.gremlin.groovy.jsr223.GroovyCompilerGremlinPlugin: {classMapCacheSpecification: "initialCapacity=1000,maximumSize=10000"} " ?
and 1000 and 10000 are quantified as ?
Is above plugin supported for 3.4.6 ?

worker thread pool of 1, gremlin pool of 1 and boss thread pool of 1 ?
Thanks @spmallette for answering the query. Is there a ideal configuration mentioned for production systems, where we have 50millions+ vertices and edges, for fast query processing ?
