So I can see similar ticket 80178 without solution.
I have a field that is a number and I format that using Kibana to show it as a Duration.
But I'm unable to find where exactly is Kibana storing that information.
I can't find it in _mappings, _settings or as a content of the .kibana index. It is also not exported as json from Export everything. However when I delete .kibana index and recreate it by restarting kibana the field format in kibana ui is gone so it has to be somewhere in .kibana index, but where? Which api could I call?
I found this https://github.com/elastic/kibana/issues/12756 as well but I have nothing in fieldFormatMap.
I want to have this predefined for out stock installation in docker so it doesn't have to be setup at every installation.
