[Breaking change] Remove map.regionmap.* kibana.yml settings #81704
Description
Change description
Which release will ship the breaking change?
8.0
Describe the change. How will it manifest to users?
Remove map.regionmap.* kibana.yml settings. map.regionmap configures vector layers that are used by Region map visualizations and Maps application layers for choropleth maps. The vector layers are static GeoJSON files hosted by external HTTP servers.
Region map visualizations will be removed in 8.0 and thus not effected by the changes. With the introduction of GeoJSON Upload, Maps users should index the vector layers in Elasticsearch and use Elasticsearch as the vector layer source instead of layers provided by map.regionmap.
How many users will be affected?
What can users do to address the change manually?
Existing maps using map.regionmap layers will open but show an error for any layers using map.regionmap configuration. Users can remove the map.regionmap layer and recreate the choropleth layer by using GeoJSON Upload to index their static vector data into Elasticsearch. Users can then create a choropleth layer from the indexed vector data.
How could we make migration easier with the Upgrade Assistant?
It is not possible to use Upgrade Assistant since the migration requires indexing vector layers into elasticsearch.
Are there any edge cases?
