After installing Apache Arrow Server using the documented process on the following link:

https://neo4j.com/docs/graph-data-science/current/installation/installation-apache-arrow/

Running CALL gds.debug.arrow() returns a running state as FALSE

neo4j@neo4j> CALL gds.debug.arrow();

Troubleshooting

Review the debug.log or neo4j.log, the following errors are logged:

debug.log

2023-03-03 14:28:38.956+0000 WARN [c.n.g.a.GdsFlightServer] The GDS Flight Server is enabled but the library is not licensed. The GDS Flight Server will not be started.

neo4j.log

2023-03-03 14:28:38.956+0000 WARN The GDS Flight Server is enabled but the library is not licensed. The GDS Flight Server will not be started.

Solution

The above logging indicates that a GDS Enterprise license is not installed correctly. This is required as this feature is only part of Neo4j GDS Enterprise Edition and is not available in Neo4j GDS Community Edition. 

Neo4j GDS editions are documented on the following link:
