QUESTION

"Write" Transactions don't work when using C#/Node.js with Amazon Neptune

Asked 2022-Mar-03 at 15:24

I am able to connect to Neptune and was able to add some data to it with no issues. However, when I tried the code at https://tinkerpop.apache.org/docs/current/reference/#gremlin-dotnet-transactions it doesn't seem to work. I receive following error:

"Received data deserialized into null object message. Cannot operate on it."

I even jumped to a JS sample (https://tinkerpop.apache.org/docs/current/reference/#gremlin-javascript-transactions) and tried again. It doesn't work either.

What am I missing?

At the time of this writing, Amazon Neptune only has support for TinkerPop version 3.4.11. The "traversal transactions" semantics using tx(), that you are referencing, is new as of 3.5.2 that was released by Apache TinkerPop in mid January 2022.

Transactions are typically only required when you need to submit multiple queries but have all of the queries bounded within a single commit, or with rollback if one of the queries were to fail. If you don't need this, then each Gremlin query sent to Neptune behaves as a single transaction.

If you do need transaction-like behavior in 3.4.11, here's a link to the documentation on how to do that in Neptune using Gremlin sessions: https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-sessions.html

If you don't need transactions, then here are examples of interacting with Neptune by submitting individual queries:

QUESTION

Gremlin Translator returning error: "Cannot read property 'length' of undefined"

Asked 2021-Jun-21 at 10:57

I'm trying to use the Translator feature as described here: https://tinkerpop.apache.org/docs/3.4.11/reference/#translators

But I get an error: "Cannot read property 'length' of undefined"

I traced it back to this line in the Gremlin source: https://github.com/apache/tinkerpop/blob/b84c3ece2a584f6634f1586f4b84c4e1c349595d/gremlin-javascript/src/main/javascript/gremlin-javascript/lib/process/translator.js#L53

It looks like instructions is coming back undefined.

Here is the code I'm testing with:

You are doing what the documentation says and I think that's the desired way the Translator should be used but the translate() function actually requires a Bytecode object therefore proper usage should be:

QUESTION

Gremlin DSL usage errors within `repeat` step

Asked 2020-Feb-07 at 07:48

We are using gremlin-javascript and have recently started to define a DSL to simplify our queries.

I am not sure if I've overlooked some caveat, but when attempting to use DSL methods within a repeat step, I consistently receive (...).someDslFunction is not a function errors, but using the same DSL function outside of repeat works without issue.

Here is a short (contrived) DSL definition that produces this issue:

I assume that the problem is that it's because you start your traversal with __ which is the standard TinkerPop spawn for anonymous traversals. As a result you get a GraphTraversal created rather than your CustomDSLTraversalSource. The TinkerPop gremlin-javascript documentation states that:

steps that are made available on a GraphTraversal should also be made available as spawns for anonymous traversals

So you probably should have your own version of __ that returns the CustomDSLTraversalSource. If you want to see more explicitly where things are going wrong, see in the code that callOnEmptyTraversal() returns GraphTraversal and obviously your DSL methods won't be available on that class.
