A Neo4j database copy tool over bolt

A development tool useful to copy the data from a Neo4j database to another Neo4j database. Databases can be local or remote. As the copy is done through the Neo4j driver, no admin access to Neo4j is required.

This is useful to copy things around, for example test/reference data from an environment to another.

It has been tested on small to average database sizes.

Note: data deletion, users, indexes, constraints are not handled.

Building

Building / running requires Java 17+.

mvn clean package -DskipTests

The resulting app can be found in the target directory.
