Technical Summary:

• Removed compatibility with multi-type indices
• ES Plugin status will be red when multiple, or zero, types are detected
  • devs will need to delete their kibana index or use the migration assistant UI to upgrade the index while still using 5.x
• the ensureTypesExist part of the health check is now patchKibanaIndex, it no longer creates types and applies all patches in a single request
• SavedObjectClient
  • Fixed #find() support for filtering on specific fields
    • improved test coverage by breaking createFindQuery() into pieces and testing each individually
  • Removed normalize_es_doc as the abstractions was subtly different for each method and seemed better implemented inline
  • fields and searchFields must be arrays after the API.
    • respective query params will always be cast to an array by using Joi.array().single()
• server/mappings module added
  • includes what used to be ui/ui_mappings
  • exposes an instance of IndexMappings on kbnServer that should not be used by code outside of the uiExports
    • all mapping properties (except for the defaults) should be defined with uiExports type mappings in a plugin
  • defines server.getKibanaIndexMappingsDsl(), which was previously exposed via kibana.uiExports.mappings.getCombined()
    • code that used to pass around the mappings object and the server now just pass around the server
  • added helpers for reading mapping DSL
  • kbnServer.mappings which is the instance of IndexMappings maintained by the kibana server and extended by the UiExports class using kbnServer.mappings.addRootProperties()
• when in the context of mappings management/es index types, SavedObject "types" are now disambiguated from es types by calling them the "root properties" of the "root type" of the "kibana index mappings dsl"
• ui
  • SavedObjectLoader now sends * (not undefined*) when search string is undefined
  • Converted several uses of indexPattern.id to indexPattern.title, where appropriate
  • Added a mapBreadcrumbs() argument to routes that will allow them to set the display value for the index pattern id in the breadcrumb as the title of the index pattern
  • Removed a stray async function that snuck into angular code
  • When an index pattern doesn't have a title, the id is assumed to be the title (BWC)
• functional tests
  • updated kibanaServer.uiSettings to use SavedObjectClient
  • added kibanaIndex service that fetches a copy of the kibanaIndex mapping and exposes the name of the kibana index to tests, should they need it
  • retry is now in the common services, along with kibanaServer and kibanaIndex

Release Note:

Starting in Elasticsearch 6.0, you are no longer able to create new indices with multiple index types. To accomplish the same effect as index types, a new type field was added to identify the document and the value mapped under the index to allow for strict mapping.

Example

"mappings": {
  "dashboard": {
    "properties": { ... }
  }
}

is now

"mappings": {
  "doc": {
    "properties": {
      "type": { "type": "keyword" },
      "dashboard": {
        "type": "object",
        "properties": { ... }
      }
    }
  }
}
