POST <node_ip>:9200/_reindex?scroll=120m&timeout=120m&requests_per_second=10
{
  "source": {
    "index": "pcom",
    "size":50
  },
  "dest": {
    "index": "pcom_temp"
  }
}

Hi all

And we found in the same index , if we reindex less data(about less than 10k docs), success rate goes up obviously.

Thanks for help

@lizhu, it does look odd. Which version of Elasticsearch are you on?

I would advice against the requests_per_second=10, since it really means documents per second and thus would take around 10 hours to complete with that.

@HenningAndersen Thank you, es version: 6.8.0
As shown in the picture, I did not set url parameter requests_per_second, however the err is also returned many times.
