Local (non-replicating) Documents
=================================
The Local (non-replicating) document interface allows you to create local
documents that are not replicated to other databases. These documents can be
used to hold configuration or other information that is required specifically
on the local CouchDB instance.
Local documents have the following limitations:
- Local documents are not replicated to other databases.
- Local documents are not output by views, or the :ref:`api/db/all_docs` view.
From CouchDB 2.0, Local documents can be listed by using the /db/_local_docs
endpoint.
Local documents can be used when you want to store configuration or
other information for the current (local) instance of a given database.
A list of the available methods and URL paths are provided below:
+--------+------------------------+--------------------------------------------+
| Method | Path | Description |
+========+========================+============================================+
| GET, | /db/_local_docs | Returns a list of all the |
| POST | | non-replicated documents in the database |
+--------+------------------------+--------------------------------------------+
| GET | /db/_local/id | Returns the latest revision of the |
| | | non-replicated document |
+--------+------------------------+--------------------------------------------+
| PUT | /db/_local/id | Inserts a new version of the |
| | | non-replicated document |
+--------+------------------------+--------------------------------------------+
| DELETE | /db/_local/id | Deletes the non-replicated document |
+--------+------------------------+--------------------------------------------+
| COPY | /db/_local/id | Copies the non-replicated document |

.. http:get:: /{db}/_local_docs
:synopsis: Returns a built-in view of all local (non-replicating) documents
in this database
Returns a JSON structure of all of the local documents in a given
database. The information is returned as a JSON structure containing meta
information about the return structure, including a list of all local
documents and basic contents, consisting the ID, revision and key. The key
is the from the local document's ``_id``.

Ignored if ``include_docs`` isn't ``true``. Default is ``false``.
:query boolean descending: Return the local documents in descending by
key order. Default is ``false``.
:query string endkey: Stop returning records when the specified key is
reached. *Optional*.
:query string end_key: Alias for ``endkey`` param.
:query string endkey_docid: Stop returning records when the specified
local document ID is reached. *Optional*.

*Optional*.
:query string start_key: Alias for ``startkey`` param.
:query string startkey_docid: Return records starting with the specified
local document ID. *Optional*.
:query string start_key_doc_id: Alias for ``startkey_docid`` param.
:query boolean update_seq: Response includes an ``update_seq`` value
indicating which sequence id of the underlying database the view
reflects. Default is ``false``.
:>header Content-Type: - :mimetype:`application/json`
- :mimetype:`text/plain; charset=utf-8`
:>json number offset: Offset where the local document list started
:>json array rows: Array of view row objects. By default the information
returned contains only the local document ID and revision.
:>json number total_rows: Number of local documents in the database. Note
that this is not the number of rows returned in the actual query.
:>json number update_seq: Current update sequence for the database

.. http:post:: /{db}/_local_docs
:synopsis: Returns a built-in view of all local (non-replicating) documents
in this database
:method:`POST` `_local_docs` functionality supports identical parameters and behavior
as specified in the :get:`/{db}/_local_docs` API but allows for the query string
parameters to be supplied as keys in a JSON object in the body of the `POST` request.

The returned JSON is the all documents structure, but with only the
selected keys in the output:
