summary: |-
  This recipe takes sample movie and rating data, builds a graph, and alerts 
  when an actor is also the director of a movie.

  This recipe is part of the Quine Ingest Stream blog series. This time, we'll 
  work with `CSV` data exported from IMDb to answer the question; *"Which actors 
  have acted in and directed the same movie?"*

Scenario

In this scenario, Quine combines data from multiple CSV files into one graph. As the graph is formed, a standing query matches and reports every instance of when a person is both the actor and director of a movie.

Sample Data

The sample data for this recipe is provided in two csv files that were exported from a relational database.

File 1: movieData.csv contains the Person, Movie, and Join rows.

Download movieData.csv

File 2: ratingData.csv contains rows of ratings.

Download ratingData.csv

Click on the buttons above to download the sample data into the same directory where Quine will be run.

How it Works

This recipe parses the CSV files using ingest streams. We used multiple ingests streams to parse the movieData.csv file to highlight how the Cypher acts on each data structure. Creating a single ingest stream for the movie data would be more efficient.

The recipe ingests the CSV files to create the following graph shape.

Movie and Genre Nodes

The first ingest stream matches the movieData.csv file's rows containing Movie entities. These rows are parsed, turned into Movie and Genre nodes, and filled with properties. Genre nodes are connected to Movie nodes in the graph.

Person Nodes

The second ingest stream matches the movieData.csv file's rows containing Person entities. These rows are parsed, turned into Person nodes, and filled with properties.

Role Nodes

The third ingest stream matches the movieData.csv file's rows containing Join entities that have Acting in the Work column. These rows are parsed, turned into Role nodes, filled with properties, and connected to the graph. Additionally, the ACTED_IN relationship is set between the Person and Movie nodes.

Directed Nodes

The fourth ingest stream matches the movieData.csv file's rows containing Join entities that have Directing in the Work column. These rows are parsed and the DIRECTED relationship is created between the Person and Movie nodes.

Rating Nodes

The fifth ingest stream matches rows from the ratingsData.csv file to create User and Rating nodes, fill them with parameters, and connect them into the graph.

YAMLJSON

  }
}

Acted and Directed

A standing query detects when an actor (Person) has both the ACTED_IN and DIRECTED relationship to the same Movie.

When a pattern match is found, the ActedDirected relationship is created between the Person and Movie nodes in the graph, and an alert is written into the ActorDirector.jsonl file.

YAMLJSON

    type: Cypher
    mode: MultipleValues

Running the Recipe

java \
-jar quine-1.6.2.jar -r movieData.yaml\
--recipe-value movie_file=movieData.csv \
--recipe-value rating_file=ratingData.csv 

Tip

This recipe will create an ActorDirector.jsonl file in the local directory that you should remove before each run. We found it easier to launch Quine using the following shell script so that we didn't forget to clean up output from previous runs.

run-recipe.sh

#!/bin/bash

[ -f ActorDirector.jsonl ] && rm ActorDirector.jsonl

java \
-jar quine-1.6.2.jar -r movieData.yaml\
--recipe-value movie_file=movieData.csv \
--recipe-value rating_file=ratingData.csv

Launching Quine directly or using run-recipe.sh will produce output similar to this.
