neo4j: what are org.neo4j.driver.types package classes for?

Asked 2021-Nov-25 at 16:02

I'm eager to figure out the what do org.neo4j.driver.types stand for?

This package becomes available with neo4j driver (org.neo4j.driver:neo4j-java-driver).

Under this package there are classes like Entity, Node, RelationShip, ....

Are those classes intended to be used like some kind of ORM(OGM).

Note: I'm not using neo4j-ogm. I'm only using org.neo4j.driver:neo4j-java-driver dependency.

I'm eager to figure out the what do org.neo4j.driver.types stand for?

These are domain objects for neo4j DB ... they are needed by driver to store/load data to/from the database. I would say they are similar to classes like 'ResultSet` for JDBC.

The driver needs these classes to "explain" a write operation to neo4j and to "enterpret" the response.

(If you only plan to use the driver, you do not need Neo4j OGM)

Once the session is closed, you cannot access the driver's Result instance. You should instead iterate over the records while the session is open and return the result you want, something like:

We need to use auto-commit transactions in this case. As the documents says:

Auto-commit transactions are the only way to execute USING PERIODIC COMMIT Cypher statements.

You need to add your task application properties into an application metadata that Spring Cloud Data Flow knows how to extract and make them available.

You can refer this page that walks you through how to add metadata.

Also, you can check this sample configuration as a reference on how to add such metadata.
