Is enabling docValues and disabling index possible

Elastic Stack Elasticsearch
1

Hi ,

I have a situation where a field is only used for aggregation , its never
used for searching.
In such cases , it doesn't make sense for this field to go to lucene
reverse index.
Rather if it can be only maintained in fieldData or docValues alone . that
would save me some good amount of space and might optimize performance.

Is this possible ?

Thanks
Vineeth

Yes, you can have a field that is not indexed but has doc values. In that
case, elasticsearch will build columnar storage for that field, but no
inverted index.
