Orientdb: Export/Import wirft Ausnahme: „Invalid Format gefunden ungestützt Tag‚brokenRids‘.“

Question

Versuch OrientDB's export/import functionality zu verwenden, aber ich erhalte immer Fehler, die beide von der Kommandozeilen-Client und durch die JAVAAPI mit

Erstellen einer Datenbank mit minimalem Inhalt, dann

export database /tmp/db.export -excludeAll -includeClass="asdf" 

importieren dann mit

import database /tmp/db.export.gz 

ergibt die Fehlermeldung Invalid format. Found unsupported tag 'brokenRids' aufrufen. Hier ist die vollständige Konsole zu reproduzieren:

Jede Hilfe sehr geschätzt.

EDIT: die exportierten Daten sieht wie folgt aus:

gunzip -c /tmp/test_export_import.export.gz 
{"records":[{"@type":"d","@rid":"#17:0","@version":1,"@class":"asdf","one":"two","three":"four"}],"brokenRids":[]} 

Answer 1

es bedeutet, dass Sie versuchen, Daten zu importieren, die von einer älteren Version von ODB exportiert wurden. Wir unterstützen die Kompatibilität von der Zukunft zu den früheren Versionen nicht, unterstützen die Kompatibilität jedoch in entgegengesetzter Weise.
