        Parameters
        ----------
        name : str
            The name of the database.
        url : str
            The url of the CouchDB server formatted as `scheme://user:password@host:port`. For example:

                "http://user:password@127.0.0.1:5984"
                "https://couchdb.example.com"
        port : int
            The port of the CouchDB server. Can also be supplied via the url.
        user : str
            The CouchDB admin username. Can also be supplied via the url.
        password : str
            The CouchDB admin password. Can also be supplied via the url.
        disable_ssl_verification : bool
            Controls whether to verify the server's TLS certificate. Set to `True` when connecting
            to a server with self-signed TLS certificates. Default `False`.
        auth_method : str
            Authentication method. Choices are `cookie` or `basic`.
            Default is `couchdb3.utils.DEFAULT_AUTH_METHOD`.
        timeout : int
            The default timeout for requests. Default c.f. `couchdb3.utils.DEFAULT_TIMEOUT`.
        session : httpx.AsyncClient
            A specific async client to use. Optional — if not provided, a new client will be

        Returns a sorted list of changes made to documents in the database. Only the most
        recent change for a given document is included.

        When `doc_ids` is provided the request is sent as ``POST /{db}/_changes`` with
        ``filter=_doc_ids``. When `selector` is provided it is sent as
        ``POST /{db}/_changes`` with ``filter=_selector``. All other cases use
        ``GET /{db}/_changes``.

        .. note::
            ``feed='continuous'`` and ``feed='eventsource'`` are **not** supported by this
            method. Passing either value raises :class:`ValueError`. Streaming feeds will be
            addressed in a future ``changes_stream()`` method.

        Parameters
        ----------
        doc_ids : list[str]
            List of document IDs to filter the changes feed. Triggers a POST request with
            ``filter=_doc_ids``. Mutually exclusive with `selector`.
        conflicts : bool
            Include conflicts information. Only effective when `include_docs` is `True`.
        descending : bool
            Return changes in descending sequence order. Default `False`.
        feed : str
            Feed type. Supported values: ``'normal'`` (default), ``'longpoll'``.
            ``'continuous'`` and ``'eventsource'`` are not supported.
        filter : str
            Name of a filter function (``'design_doc/filter_name'``, ``'_design'``, or
            ``'_view'``). Do not pass ``'_doc_ids'`` or ``'_selector'`` manually — use the
            `doc_ids` / `selector` parameters instead.
        heartbeat : int
            Milliseconds between heartbeat newlines for ``longpoll`` feed.
        include_docs : bool
            Include the associated document with each result. Default `False`.
        attachments : bool
            Include Base64-encoded attachment content when `include_docs` is `True`.
        att_encoding_info : bool
            Include encoding info in attachment stubs when `include_docs` is `True`.
        limit : int
            Maximum number of rows to return.
        since : str
            Return only changes after the given update sequence. Use ``'now'`` to get only
            future changes.
        style : str
            Revision style. ``'main_only'`` (default) or ``'all_docs'``.
        timeout : int
            Maximum milliseconds to wait for a change (``longpoll`` only).
        view : str
            View function to use as a filter (requires ``filter='_view'``).
        seq_interval : int
            Calculate update sequence every N results (reduces server load on large
            sharded databases).
        selector : dict
            Mango selector to filter documents. Triggers a POST request with
            ``filter=_selector``. Mutually exclusive with `doc_ids`.

        Returns
        -------
        dict : A dictionary with the following keys.

          - ``last_seq`` (`str`) — last change update sequence
          - ``pending`` (`int`) — count of remaining items in the feed
          - ``results`` (`list`) — list of change objects, each with ``id``, ``seq``,

        """
        Stream changes made to documents in the database using the ``continuous`` changes
        feed. Unlike `AsyncDatabase.changes`, this does not buffer the whole response — it
        yields each change object as it arrives over a persistent HTTP connection.

        This method must be used as an async context manager. The underlying connection is
        kept open for the duration of the ``async with`` block and closed automatically on
        exit.

        When `doc_ids` is provided the request is sent as ``POST /{db}/_changes`` with
        ``filter=_doc_ids``. When `selector` is provided it is sent as
        ``POST /{db}/_changes`` with ``filter=_selector``. All other cases use
        ``GET /{db}/_changes``.

        Parameters
        ----------
        doc_ids : list[str]
            List of document IDs to filter the changes feed. Triggers a POST request with
            ``filter=_doc_ids``. Mutually exclusive with `selector`.
        conflicts : bool
            Include conflicts information. Only effective when `include_docs` is `True`.
        descending : bool
            Return changes in descending sequence order. Default `False`.
        filter : str
            Name of a filter function (``'design_doc/filter_name'``, ``'_design'``, or
            ``'_view'``). Do not pass ``'_doc_ids'`` or ``'_selector'`` manually — use the
            `doc_ids` / `selector` parameters instead.
        heartbeat : int
            Milliseconds between heartbeat newlines for ``continuous`` feed.
        include_docs : bool
            Include the associated document with each result. Default `False`.
        attachments : bool
            Include Base64-encoded attachment content when `include_docs` is `True`.
        att_encoding_info : bool
            Include encoding info in attachment stubs when `include_docs` is `True`.
        limit : int
            Maximum number of rows to return. On the ``continuous`` feed this caps the
            number of emitted rows but does not close the connection on CouchDB 3.3.x —
            the stream keeps blocking until the caller breaks out of the loop or the
            server times out.
        since : str
            Return only changes after the given update sequence. Use ``'now'`` to get only
            future changes.
        style : str
            Revision style. ``'main_only'`` (default) or ``'all_docs'``.
        timeout : int
            Maximum milliseconds to wait for a change, sent to CouchDB as the ``timeout``
            query parameter (not the HTTP connection timeout). Default `None` (no timeout).
        view : str
            View function to use as a filter (requires ``filter='_view'``).
        seq_interval : int
            Calculate update sequence every N results (reduces server load on large
            sharded databases).
        selector : dict
            Mango selector to filter documents. Triggers a POST request with
            ``filter=_selector``. Mutually exclusive with `doc_ids`.

        Yields
        ------
        AsyncIterator[dict] : An async iterator yielding change objects, each with ``id``,
            ``seq``, ``changes``, and optionally ``deleted`` / ``doc``.

        Raises
        ------
        CouchDBError
            If both `doc_ids` and `selector` are provided.

        Notes
        -----
        - The stream stays open indefinitely. Break out of the loop (or exit the
          ``async with`` block) to close the connection.
        - When ``limit`` is set, CouchDB's documentation mentions that the feed may end
          with a terminal ``{"last_seq": "..."}`` object that has no ``id`` key. This
          object is not emitted by CouchDB 3.3.x and its presence may vary by server
          version, so callers indexing ``row["id"]`` should guard against rows without an
          ``id`` key.

url : str

The url of the CouchDB server formatted as scheme://user:password@host:port. For example:

"http://user:password@127.0.0.1:5984"
"https://couchdb.example.com"

port : int

The port of the CouchDB server. Can also be supplied via the url.

user : str

The CouchDB admin username. Can also be supplied via the url.

password : str

The CouchDB admin password. Can also be supplied via the url.

disable_ssl_verification : bool

Controls whether to verify the server's TLS certificate. Set to True when connecting to a server with self-signed TLS certificates. Default False.

auth_method : str

Authentication method. Choices are cookie or basic. Default is DEFAULT_AUTH_METHOD.

timeout : int

The default timeout for requests. Default c.f. DEFAULT_TIMEOUT.

session : httpx.AsyncClient

A specific async client to use. Optional — if not provided, a new client will be initialized.

_server : AsyncServer

The owning AsyncServer instance. Set internally by AsyncServer.get() to keep the server alive for the lifetime of this database object. Not part of the public constructor API — pass None (default) when constructing an AsyncDatabase directly.

    att_encoding_info : bool
        Include encoding info in attachment stubs when `include_docs` is `True`.
    limit : int
        Maximum number of rows to return. On the ``continuous`` feed this caps the

        Return only changes after the given update sequence. Use ``'now'`` to get only

    Notes
    -----
    - The stream stays open indefinitely. Break out of the loop (or exit the

    - When ``limit`` is set, CouchDB's documentation mentions that the feed may end
      with a terminal ``{"last_seq": "..."}`` object that has no ``id`` key. This
      object is not emitted by CouchDB 3.3.x and its presence may vary by server

      ``id`` key.

Parameters

doc_ids : list[str]

List of document IDs to filter the changes feed. Triggers a POST request with filter=_doc_ids. Mutually exclusive with selector.

conflicts : bool

Include conflicts information. Only effective when include_docs is True.

descending : bool

Return changes in descending sequence order. Default False.

filter : str

Name of a filter function ('design_doc/filter_name', '_design', or '_view'). Do not pass '_doc_ids' or '_selector' manually — use the doc_ids / selector parameters instead.

Include encoding info in attachment stubs when include_docs is True.

limit : int

Maximum number of rows to return. On the continuous feed this caps the number of emitted rows but does not close the connection on CouchDB 3.3.x — the stream keeps blocking until the caller breaks out of the loop or the server times out.

since : str

Return only changes after the given update sequence. Use 'now' to get only future changes.

style : str

Revision style. 'main_only' (default) or 'all_docs'.

view : str

View function to use as a filter (requires filter='_view').

seq_interval : int

Calculate update sequence every N results (reduces server load on large sharded databases).

This object is not emitted by CouchDB 3.3.x and its presence may vary by server version, so callers indexing row["id"] should guard against rows without an id key.

Examples

>>> async with db.changes_stream(since="now") as stream:
...     async for row in stream:
...         print(row["id"], row["seq"])
