Examples for different graph dbs

Gremlin-Scala examples

A collection of example projects and recipies for Gremlin-Scala that you can use as templates for your own tinkering.

Tinkergraph

• MovieLens - a large collection of traversals based on a presentation by Marko Rodriguez and Daniel Kuppitz

Gremlin-Server

Demonstrate setup with a remote graph db.

• Simple traversal

OrientDB

• Simple traversals

Neo4j

• Simple traversal
• Indexes
• Shortest path - Blog post

Neo4j Bolt protocol

• Simple traversal

DSE graph

Note: to start DSE, first run: docker run --name dseg51 -p 9042:9042 -d luketillman/datastax-enterprise:5.1.1 -g To stop DSE, run docker stop dseg51. To start it again, run docker start dseg51.

• Simple traversal, bulk scenario

Janusgraph

• Simple traversal

Sqlg

Note: to run PostgresSpec, first run docker run -e -d POSTGRESQL_PASSWORD=pass -p 9096:5432 postgres

• Simple traversal (H2)
• Simple traversal (PostgreSQL)

Usage

First install jdk 8 and configure it to be your JAVA_HOME and in your path (check with echo $JAVA_HOME and java -version).
