This change adds a dynamic cluster setting named `indices.id_field_data.enabled`. When set to `false` any attempt to load the fielddata for the `_id` field will fail with an exception. The default value in this change is set to `false` in order to prevent fielddata usage on this field for future versions but it will be set to `true` when backporting to 7x. When the setting is set to true (manually or by default in 7x) the loading will also issue a deprecation warning since we want to disallow fielddata entirely when https://github.com/elastic/elasticsearch/issues/26472 is implemented. Closes #43599 |
