movies-neo4j
It's a simple api build on top of Neo4j Database, and it's movie database sample.
The application uses the neo4j-java-driver-spring-boot-starter to manager the connection with the
database by default. Thus, it uses the official driver.
However, an alternative version the driver implemented under the package
com.neo4j.driver could be used by setting the environment variable
NEO4J_EXPERIMENTAL to true. This version of the drivers doesn't fulfil all the
capabilities of the official driver, but it implements part of the interfaces:
- Transaction
- Result
- Record
- Value
- Node
Because of this, the swapping between the two implementations only impacts
the configuration class TransacationFactoryConfig.
PS: Probably there are some corner cases which the new alternative driver will not handle well because of some unhandled packing and unpacking of data or something like that.
WARNING: The alternative version of the driver is an exercise to understand how the Bolt protocol works, and it should be not used in production code
Commands
Build:
docker-compose build
Run the project without upload dataset:
docker-compose up -d neo4j application
Upload dataset:
docker-compose up dataset
Run the project and upload dataset:
docker-compose -f docker-compose.yml -f docker-compose.dataset.yml up -d
To enable the experimental transaction, you should pass also -f docker-compose.experimental.yml to the docker-compose up command
Stop the service
docker-compose down
Alternatively, the project could run using:
docker-compose up -d neo4j to start the database
./mvnw spring-boot:run to build and run the application
It's useful for development.
