Hello,
Objective : Compare last data sent by injector with the last document inserted in index ES.
About last document inserted in ES index, how i can show it ?
In index mapping, we have field called Connect\_time, we can use it to show most recent document.
Thanks for help.
Best Regards
Romain

There's nothing IMO which does that automatically.
You can just provide yourself a timestamp set to when you sent the document to elasticsearch.

Sort by your Connect\_time fields and size: 1
