==== Aggregating and sorting on `_id` is deprecated
It's possible to aggregate and sort on the built-in `_id` field by loading an
expensive data structure called fielddata. This was deprecated in 7.6 and will
be disallowed by default in 8.0. As an alternative, the `_id` field's contents
can be duplicated into another field with docvalues enabled (note that this
does not apply to auto-generated IDs).

The `sparse_vector` field type has been deprecated and will be removed in 8.0. The `sparse_vector` field type has been deprecated and will be removed in 8.0.
