astradb-janusgraph-demo

Introduction

This is a demo app which showcases

• connecting JanusGraph setup to DataStax AstraDB as the backend

• Setting up the Schema and Loading test data into JanusGraph

• Sample queries via gremlin-console

• The demo app uses simulates the Identity Resolution use case which is the process of matching identifiers across devices and touchpoints to a single profile which helps build a cohesive, omnichannel view of a consumer, enabling brands to deliver relevant messaging throughout the customer journey

• The underlying data source for IDR is generally an Identity Graph (IDG) which is a profile database housing all known identifiers correlated to individuals. The IDG also stores the metadata about the identifiers

• An IDG as below for a single user who is represented via multiple identifiers all connected to each other directly or transitively

How to run

• Update conf directory files

  • resources/executorConf.json

    • Sample values from resources folder are added

  • resources/janusgraph-cql.properties

  storage.cql.keyspace=\keyspace-name\
  storage.cql.internal.file-configuration=/path/to/astra.conf
  

  • resources/astra.conf

  secure-connect-bundle = "/path/to/secure/bundle/zip/file"
  username = "clientId"
  password = "clientSecret"
  

• Build the codebase

  ./gradlew shadow
  

• Run the Loader

  • The loader sets up graph schema and then loads the data

    java -jar build/libs/astradb-janusgraph-demo-app-1.0-SNAPSHOT-all.jar <path-to-executorConf.json>
    

• Interacting with the graph

  • We have collated queries in resources/queries.txt for playing with the demo data loaded via gremlin-console
