fgxue/d3-gremlin

A Spring Boot REST API which executes queries in gremlin, using the Tinkerpop Java API, and returns data, nodes, links and options, in a format acceptable to the vue-d3-network component.

d3-gremlin

A Java (Spring Boot) REST API which executes queries using gremlin on graph data resources to produce data, nodes, links and options, in a format acceptable to the vue-d3-network component

Execution

This is a Spring Boot app which can be executed with the included spring-boot maven plugin like so

<plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <jvmArguments> -Dspring.profiles.active=localGraph -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 </jvmArguments> </configuration> </plugin>

Or by executing the package .jar file from from the terminal and specifying a complete set of production configurations

java -jar d3-gramlin-<version> --spring.config.name=/path/to/app/properties Or just the profile which defines the connection type to the underlying graphDB

java -jar d3-gramlin-<version> --spring.profiles.active=localGraph

There are various built in profiles which will provide a connection to a graphDB and return a traversal source via the GraphTraversalSourceProvider stereotype

• localGraph
• remoteGraph

localGraph uses the GraphTraversalSourceProviderTinkerGraphImpl class which will load a TinkerGraph from a graphML file at the location specified by the tinkergraph.graphml.file.path property remoteGraph uses the GraphTraversalSourceProviderRemoteImpl class which will provide a connection to a remote graph at the end point and port specified in the following properties

• gremlin.cluster.end-point
• gremlin.cluster.port

Note: the integrationTest profile will run a local TinkerGraph at a fixed location specified in test-resources

For EC2 UserData - execution on start up, use nohup in the following script #!/bin/bash nohup /usr/bin/java -jar /home/ec2-user/returns-1.0.jar --spring.config.name=/home/ec2-user/lymm.application.properties & > /home/ec2-user/nohup.out
