Update a title of the `<my-pattern>` index pattern:

[source,sh]
--------------------------------------------------
$ curl -X POST api/saved_objects/index-pattern/my-pattern
{
  "index_pattern": {
    "title": "some-other-pattern-*"
  }
}
--------------------------------------------------
// KIBANA

Customize the update behavior:

[source,sh]
--------------------------------------------------
$ curl -X POST api/saved_objects/index-pattern/my-pattern
{
  "refresh_fields": true,
  "index_pattern": {
    "fields": {}
  }
}
--------------------------------------------------
// KIBANA


All update fields are optional, but you can specify the following fields:

[source,sh]
--------------------------------------------------
$ curl -X POST api/saved_objects/index-pattern/my-pattern
{
  "index_pattern": {
    "title": "...",
    "timeFieldName": "...",
    "sourceFilters": [],
    "fieldFormats": {},
    "type": "...",
    "typeMeta": {},
    "fields": {},
    "runtimeFieldMap": {}
  }
