valueMap and Multivalues
I agree with this. A DSL can also help to enforce the use of known best patterns and so on

valueMap and Multivalues
DSLs and language design are my thing, I was thinking about such a thing for my own specialized data to make it easier for our own people to come up with a traversal. I suppose a more general DSL could be written too. I wonder though if such a thing perhaps adds complexity that isn't need?

Straightforward way to render a force directed graph svg/png
I suppose that you could just generate a .dot file and use the sfdp renderer with Graphviz. It means writing a bit of code, but it is simply an iteration through the results and generating a text file, then executing the dot command.

AWS Neptune bulk load notifications
Thank you for looking in to it @triggan - it will be just my luck that I ahve written my own code to call the endpoints and then you guys release an offical version three days later 😉

My other request would be to incorporate the various https endpoint calls into the SDK (Go in my case)

Add Multiple addV() by one Iterate
Yes - that's what I meant. I get the traversal source and then use that

Add Multiple addV() by one Iterate
So, in go I have been using: t := g.Traversal(). Then adding to t in loops for say batches of 20. Rather than t := g.V() as in the above python code. I preseume then that either is OK?

Direct and indirect Edges
Just wondering why millions of A->C edges would slow A->B. Or you mean if I don't explicitly name/label the outgoing edges from A?

Direct and indirect Edges
OK - that's good reasoning. As I said in another post, the answer is likely in experimentation, which I will do. I was just wondering if there were any rule-of-thumb things to consider, and it seems that there are.

MergeV uint32 properties inserted as long
That's fine. Signed int works fine in this case, so will use that. I suppose long would actually be fine, but I suspect any Java based system will perform better with integer.

Advantage/Disadvantage of In and out edge vs one edge
Thank you, that is useful to know. This DB is fine to bind to Neptune only. I will stick with a single edge as I can always specify the label for the edge.
I guess the real answer is to test it of course.

Concurrent MergeV gremlingo - Vertex Id exists
OK - no problem. I just needed to know that this was the case and not my code having some race condition that I was not detecting. I belive that Neptune is OK with this as it does seem to lock the vertices. This is part of a batch import program, which will move to generating batch import files for Neptune anyway. The TinkerGraph is just used to make local development a bit easier. Thanks for the information.

Help Needed with Sample Method in Gremlin-Go

Concurrent MergeV gremlingo - Vertex Id exists
Probably the easiest solution might be for me to create all the vertices that will be targets of edges first. I can do that because I know what I am importing and can then avoid teh MergeV to create the edges.

Concurrent MergeV gremlingo - Vertex Id exists
Sorry - should have been more specific, just the Tinkerpop Java gremlin server. I have yet to try that code on Neptune, which is the real target.
This seems to come from the MergeV creating the actual vertex while a MergeV to create a place holder for a MergeE is also creating it. One of them wins then the other says that it already exists because I am specifying the vertex id.

Gremlingo with Neptune - Read loop error
You are correct - I think it is because I chose to use serverless and obviously that has not yet caught up. Sorry for the noise here, but maybe having this information here might save someone else a little time.
