Data view field cache
The browser caches data view field lists for increased performance. This is particularly impactful for data views with a high field count that span a large number of indices and clusters. The field list is updated every couple of minutes in typical Kibana usage. Alternatively, use the refresh button on the data view management detail page to get an updated field list. A force reload of Kibana has the same effect.
The field list might be impacted by changes in indices and user permissions.
