Hi ,
Is there any way to remove the \_id field in elastic since `_id` field requires to load a lot of data in memory . I have used mutate field but it is not removing the \_id field

You cannot do that, have a read of [https://www.elastic.co/guide/en/elasticsearch/reference/6.5/mapping-id-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/mapping-id-field.html)
