## Guide
In this guide we are going to instantiate a pre-populated mysql database and then migrate that data to a Neo4j graph database.
When docker-compose brings up the docker instances it will populate the mysql data based on sql_import/movies.sql and the Neo4j data will persist in data/databases. If you wish to clear out the Neo4j data simple shut down the containers with docker-compose down and then delete the data/databases directory.
### Start
After cloning the repo we will bring the containers all online.
``` docker-compose up -d ```
### SQL to Graph
Export the SQL tables using the output_csv.sql file.
``` docker-compose run mariadb sh -c "mysql -uroot -pexample movies -h mariadb < /data/output_csv.sql" ```
Import the CSV using CQL (cypher query language).
``` docker-compose run neo4j sh -c "neo4j-shell -c < /data/import_csv.cql" ```
### Debug
``` docker-compose run neo4j bash ```
cat /data/import_csv.cql | bin/cypher-shell -u neo4j -p neo4j --format plain
cat /data/import_csv.cql | bin/cypher-shell --format plain
