Scheduled cross-cluster _reindex

[CrystalDesignDR]

Hi,

we have various elastic cloud deployments where we would need to copy data from one cluster to another (with filters).
We found that we can do this with POST _reindex

Now to my question:
Is there a way to schedule a task right within elastic to trigger this corss cluster _reindex that gets the data from the last 7 days?
Or should such actions be performed from an outside cronjob that sends this request to elastic?

Example reindex:

POST _reindex
{
  "source": {
    "remote": {
      "host": "https://remotehost",
      "username": "elastic",
      "password": "??"
    },
    "index": "remoteindex*",
    "query": {
      "bool": {
        "filter": [
          {
            "range": {
              "@timestamp": {
                "gte": "2021-01-01T00:00:00.000Z",
                "lte": "2022-07-01T00:00:00.000Z",
                "format": "strict_date_optional_time"
              }
            }
          },
          {
            "match_phrase": {
              "labels.somelabel.keyword": "somevalue"
            }
          },
          {
            "bool": {
              "should": [
                {
                  "match_phrase": {
                    "client.somelabel2.keyword": "somevalue2"
                  }
                },
                {
                  "match_phrase": {
                    "client.somelabel3.keyword": "somevalue3"
                  }
                }
              ],
              "minimum_should_match": 1
            }
          }
        ]
      }
    }  
  },
  "dest": {
    "index": "dstindex"
  }
}

There's not, no. Generally it would be requested from outside Elasticsearch, via a cron'd script as you suggest.

It might be worth raising a feature request for this though.
