问题 In Amazon Neptune I would like to run multiple Gremlin commands in Java as a single transactions. The document says that tx.commit() and tx.rollback() is not supported. It suggests this - Multiple statements separated by a semicolon (;) or a newline character (\n) are included in a single transaction. Example from the document show that Gremlin is supported in Java but I don't understand how to "Multiple statements separated by a semicolon" GraphTraversalSource g = traversal().withRemote

问题 Is there a way to save the data in amazon aws neptune db using node js? I am running this code on a lambda. I made the connection to neptune db using the below code. const gremlin = require('gremlin'); const DriverRemoteConnection = gremlin.driver.DriverRemoteConnection; const Graph = gremlin.structure.Graph; dc = new DriverRemoteConnection('endpoint',{}); const graph = new Graph(); const g = graph.traversal().withRemote(dc); 回答1: Here's a JavaScript Lambda function that writes data to

问题 If I am building a graph on AWS Neptune with 20 million Nodes and 100 million edges, How much RAM and Disk space would I require? Can someone give me an rough order of magnitude estimate 回答1: Storage capacity in Amazon Neptune is dynamically allocated as you write data into a Neptune cluster. A new cluster starts out with 10GB allocated and then grows in 10GB segments as your data grows. As such, there's no need to pre-provision or calculate storage capacity prior to use. A Neptune cluster

问题 I am using es6 on nodejs, and am trying to execute the project() step in a gremlin query. As part of the projection, I want to extract the properties. Using gremlin console I would use valueMap() to get the properties. However, when I attempt this from javascript, I get the expected error "valueMap is not a function". Question 1: where do I import this function from? Question 2: where can I read about all of the various gremlin objects available for importing in javascript? ==================
