Ich versuche, die folgende Abfrage ausführen, um meine Knoten und Beziehungen aus einer CSV-Datei zu erstellen, die ich habe:„Kann Transaktion rückgängig zu machen“ Fehler in Neo4j

Aber ich erhalte die folgenden Fehler :
Unable to rollback transaction
Was bedeutet das und wie kann ich meine Abfrage beheben, so kann es erfolgreich ausgeführt werden?
ich jetzt erhalte die folgende Fehlermeldung:
GC overhead limit exceeded
Loswerden der "einzigartigen" in der Schaffung der Beziehungen geholfen! – Aly
froh zu helfen. Ich traue nicht "create unique". – Mvde
