Es wird nach nicht reservierten Elementen in der Indexierungswarteschlange gesucht und ein Satz wird als reserviert markiert, beginnend mit den Elementen mit dem ältesten Zeitstempel der höchsten Priorität ItemStatus. Die Prioritätsreihenfolge ist folgende:
Durch die Reservierung von Elementen wird verhindert, dass durch Abfragen aus anderen Threads sich überschneidende Sätze erstellen lassen.
Nachdem der Kunde die reservierten Artikel bearbeitet hat, sollte er sie wieder in den Status „Nicht reserviert“ versetzen. Rufe dazu entweder index, oder push mit dem Typ REQUEUE. auf.
Artikel werden nach 4 Stunden automatisch wieder verfügbar (nicht mehr reserviert), auch wenn keine Update- oder Push-Methode aufgerufen wird.
Für die Ausführung dieser API ist ein Administrator- oder Dienstkonto erforderlich. Das verwendete Dienstkonto ist dasjenige, das in der entsprechenden Datenquelle auf die Zulassungsliste gesetzt wurde.
