When using `_reindex` api in Elasticsearch, we can set scroll batch size as below

From [https://www.elastic.co/guide/en/elasticsearch/reference/6.8/docs-reindex.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/docs-reindex.html) - By default `_reindex` uses scroll batches of `1000`. You can change the batch size with the size field in the source element:

```
POST _reindex
{
  "source": {
    "index": "source",
    "size": 100
  },
  "dest": {
    "index": "dest"
  }
}

```

I was wondering if the option to `change` batch size is available when one makes use of `reindex` action in `curator` tool. From the documentation at [https://www.elastic.co/guide/en/elasticsearch/client/curator/current/reindex.html](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/reindex.html), I don't see any `batch size` parameter.

Will appreciate some inputs here.
