Hello,
I recently upgraded my ELK stack from 5.6 to 6.8.
I noticed there is now a Kibana REST API to perform CRUD operations on saved objects such as index pattern.
After using it to retrieve some index pattern I saw that there is sometimes, in the API response, a "readFromDocValues" attribute on some fields of the index pattern.
I browsed on the Kibana doc and there is no mention of "readFromDocValues". Depending on the data in my Elasticsearch node, i have sometimes this attribute in API reponse and sometimes not.
Can you provide some insights about this attribute ? Is it a Kibana metadata ? What is its purpose ?
Thanks.
Best regards.

Yes, it's Kibana metadata, and it's related to [Elasticsearch doc values](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/search-request-body.html#request-body-search-docvalue-fields).
Basically, things like date fields are read from doc values instead of queried directly from `_source`, so we can format the value in the correct timezone.
