Trying to load air-routes.graphml yields no such file or directory

If you obtained the air routes file from the same repository that you linked I noticed the file is called air-routes-latest.graphml not air-routes.graphml, could that be the problem?

Using master branch I was able to see the error you had when using an incorrect file path but then the console succeeded after I modified the file path to point to the file I downloaded from Kelvin's repository:

Hot reloading of SSL certificates in gremlin-server

It might be worth taking a look at this solution someone created which uses scheduled file based change detection https://github.com/Hakky54/java-tutorials/blob/main/instant-server-ssl-reloading-with-netty/netty-server/README.md

Trying to load air-routes.graphml yields no such file or directory

Can you try to use an absolute file path instead of relative?

Neptune, Gremlin Java & Bindings

Since tinkerpop 4 is not yet released, will it be a problem for you that Neptune will not have yet adopted the TP4 gremlin parameterization?

Neptune, Gremlin Java & Bindings

Hello @G.V() - Gremlin IDE (Arthur) is there a specific tinkerpop version you are looking to use? I am asking because tinkerpop 4.0 had some recent changes to introduce gremlin parameterization using GValues - see https://github.com/apache/tinkerpop/pull/2919

I am not sure how to use mergeE and mergeV using gremlin_python

Hello @GojosEnsei what is the intended behaviour you are looking for if the edge exists already but you do not want to set the updated value to true?

What's the significance of done: false ? (after calling .next())

Hello @Jonathan Fridja can you please provide an example of the queries you are running and what you expect the result to be? Looking at the commit you linked the done value is used to determine if the end of the traversal has been reached or not.
