Updating all documents using a dictionary as input

Hi,

I suppose script update is a good way and as far as I know there is no such out-of-the-box function for this case.

One improvement is to change the array in place. Another is to use map in params.

PUT /test_replace_id/
{
  "mappings": {
    "properties": {
      "employee_ids":{
        "type": "keyword"
      }
    }
  }
}

POST /test_replace_id/_doc/1
{
  "employee_ids": ["old1","old2"],
  "frieds_id": "old1"
}

POST /test_replace_id/_update/1
{
  "script": {
    "source": """
      for (t in params.targets){
        if (ctx._source[t] instanceof List){
          for (int j=0; j<ctx._source[t].length; j++){
            if (params.map.containsKey(ctx._source[t][j])) {
              ctx._source[t][j] = params.map.get(ctx._source[t][j])
            }
          }
        }else{
          if (params.map.containsKey(ctx._source[t])) {
            ctx._source[t] = params.map.get(ctx._source[t])
          }
        }
      }
    """,
    "params":{
      "targets": ["employee_ids","frieds_id"],
      "map": {"old1":"new1"}
    }
  }
}
