Hi,

wir testen gerade ein wenig mit ElasticSearch rum und mich wundert das die Tabelle s\_es\_backlog nach einer Synchronisation mit Elastic Search nicht geleert wird.

Ist das normal? nicht implementiert oder hat das einen speziellen Grund?

Weiß das jemand?

Hier die Antwort gefunden: [https://github.com/shopware/devdocs/blob/master/source/sysadmins-guide/elasticsearch-setup/index.md#using-and-understanding-the-data-synchronization-mechanism](https://github.com/shopware/devdocs/blob/master/source/sysadmins-guide/elasticsearch-setup/index.md#using-and-understanding-the-data-synchronization-mechanism)

Sollte man also wohl von Zeit zu Zeit zum aufräumen mal händisch abfeuern.  
Hoffe ich konnte jemand helfen 🙂
