logging and alerting inside a gremlin step
Hi @spmallette this query worked but when I put my code in production I am getting ton of {"detailedMessage":"Failed to complete operation due to conflicting concurrent operations. Please retry. 0 transactions are currently rolling back.","code":"ConcurrentModificationException","requestId":"15c91b13-772f-4a98-a7fa-35630de30679","message":"Failed to complete operation due to conflicting concurrent operations. Please retry. 0 transactions are currently rolling back."} (500)" which is causing issues in my lambda. I have heard that changing coalesce/addV to mergeV might prevent this, is it true, I almost changed to mergeV and mergeE everywhere except this particular code where I am unable to do it

logging and alerting inside a gremlin step
yeah this is really a typescript lambda and I wanted to log and alert , that a database search for a flight didnt give me a result, so I am creating a shell flight in DB and want to alert and log it in a single step asynchronously, without adding an extra blocking DB call(this is all a part of a bigger gremlin transaction gtx). Database we use is AWS Neptune. I tried several ways to log and alert it using different steps but couldn't do it. However, if I use __.fail('No data found') it prints the logs and works fine, but I dont want to do failure, I want to add the dummy record(shell flight) and log it.

Integration tests for AWS Neptune DB
Hi @spmallette @Kennh thanks for your response., yes I would run these integration tests every commit, which will spin up the graph server and allow me to test my gremlin queries in my application as a part of my gradle build , something like this https://java.testcontainers.org/modules/databases/mongodb/ or may be some docker image for neptune/tinkerGraph
