Hi, I have an index that is being populated in realtime. However, I have one field in the index which I don't need anymore. Is there anyway to delete just one field from an index for all documents? Thanks in advance. Cheers, Balaji

Hi @astrobalaji , you can use update by query to remove the field from all docs, see: https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html . You have to use a script in order to remove the field from each document.

Thanks
But the field is still in the mapping though. Is it possible to delete the field from the mapping??
