LocalStack Demo: Neptune Graph Database

Simple demo application illustrating the use of Neptune Graph DB queries locally, using LocalStack.

Prerequisites

  • LocalStack (Pro version)
  • Docker
  • Python
  • make
  • awslocal

Installing

To install the dependencies:

make install

Starting LocalStack

Make sure that LocalStack is started:

LOCALSTACK_API_KEY=... DEBUG=1 localstack start

Running

Run the scenario Python script query.py as follows:

make run

You should see some logs from the script, similar to the output below:

Creating Neptune Graph DB cluster "cluster123" - this may take a few moments ...
Connecting to Neptune Graph DB cluster URL: ws://localhost:4510/gremlin
Submitting values: [1,2,3,4]
Received values from cluster: [1, 2, 3, 4]
Existing vertices in the graph: []
Adding new vertices "v1" and "v2" to the graph
New list of vertices in the graph: [v[0], v[3]]
Deleting Neptune Graph DB cluster "cluster123"

Note: when running the scenario consecutively, it may takes some time to free the port used by Neptune.
