Re: [Neo4j] Accessing node properties with batch inserter
Paul,
that GDB instance you get is NOT supporting deletions or transactions
(it does just ignore them) it's more for reading stuff. See the
JavaDoc for the method:
/**
*
* @return a GraphDatabaseService that does not support deletion
and transactions
*/
public GraphDatabaseService getGraphDbService();
When having a Batchinserter open, please do all modifications via it ...
Cheers,
