        The bulk document API allows you to create and update multiple documents at the same time within a single
        request. The basic operation is similar to creating or updating a single document, except that you batch the
        document structure and information.

        When creating new documents the document ID (`_id`) is optional.

        For updating existing documents, you must provide the document ID, revision information (`_rev`), and new
        document values.

        In case of batch deleting documents all fields as document ID, revision information and deletion status
        (`_deleted`) are required.

        limit : int
            Maximum number of results returned. Default is `25`.
        skip : int
            Skip the first `n` results, where `n` is the value specified. Default is `0`.
        sort : Dict
             JSON array following CouchDB's [sort syntax]
             (https://docs.couchdb.org/en/main/api/database/find.html#find-sort). Default is `None`.
        fields : List[str]
            Dictionary specifying which fields of each object should be returned. If it is omitted, the entire object
            is returned. More information provided in CouchDB's [section on filtering fields]
            (https://docs.couchdb.org/en/main/api/database/find.html#find-filter).
        use_index : Union[str, List[str]]
            Instruct a query to use a specific index. Specified either as `"<design_document>"` or
            `["<design_document>", "<index_name>"]`. Default is `None`.
        conflicts : bool
            Include conflicted documents if `True`. Intended use is to easily find conflicted documents,
            without an index or view. Default is `False`.
        r : int
            Read quorum needed for the result. This defaults to 1, in which case the document found in the index is
            returned. If set to a higher value, each document is read from at least that many replicas before it is
            returned in the results. This is likely to take more time than using only the document stored locally with
            the index. Default is `None`.
        bookmark : str
            A string that enables you to specify which page of results you require. Used for paging through result
            sets. Every query returns an opaque string under the `bookmark` key that can then be passed back in a query
            to get the next page of results. If any part of the selector query changes between requests, the results
            are undefined. Default is `None`.
        update: bool
            Whether to update the index prior to returning the result. Default is `True`.
        stable : bool
            Whether or not the view results should be returned from a “stable” set of shards. Default is `None`.
        execution_stats : bool
            Include [execution statistics](https://docs.couchdb.org/en/main/api/database/find.html#find-statistics) in
            the query response. Default is `False`.

        -------
        Dict: A dictionary containing the following keys.

          - dbname (`str`) – Name of database

            Read quorum needed for the result. This defaults to 1, in which case the document found in the index is
            returned. If set to a higher value, each document is read from at least that many replicas before it is
            returned in the results. This is likely to take more time than using only the document stored locally with
            the index. Default is `None`.
        bookmark : str
            A string that enables you to specify which page of results you require. Used for paging through result
            sets. Every query returns an opaque string under the `bookmark` key that can then be passed back in a query
            to get the next page of results. If any part of the selector query changes between requests, the results
            are undefined. Default is `None`.
        update: bool
            Whether to update the index prior to returning the result. Default is `True`.
        stable : bool
            Whether or not the view results should be returned from a “stable” set of shards. Default is `None`.
        execution_stats : bool
            Include [execution statistics](https://docs.couchdb.org/en/main/api/database/find.html#find-statistics) in
            the query response. Default is `False`.
        partition: str
            An optional partition ID. Only valid for partitioned databases. (Default `None`.)

        Shows which index is being used by the query. Parameters are the same as `Database.find`.

        Parameters
        ----------
        selector : Dict
            JSON object describing criteria used to select documents. More information provided in CouchDB's section on
            [selector syntax](https://docs.couchdb.org/en/main/api/database/find.html#find-selectors).
        limit : int
            Maximum number of results returned. Default is `25`.
        skip : int
            Skip the first `n` results, where `n` is the value specified. Default is `0`.
        sort : Dict
             JSON array following CouchDB's [sort syntax]
             (https://docs.couchdb.org/en/main/api/database/find.html#find-sort). Default is `None`.
        fields : List[str]
            Dictionary specifying which fields of each object should be returned. If it is omitted, the entire object
            is returned. More information provided in CouchDB's [section on filtering fields]
            (https://docs.couchdb.org/en/main/api/database/find.html#find-filter).
        use_index : Union[str, List[str]]
            Instruct a query to use a specific index. Specified either as `"<design_document>"` or
            `["<design_document>", "<index_name>"]`. Default is `None`.
        conflicts : bool
            Include conflicted documents if `True`. Intended use is to easily find conflicted documents,
            without an index or view. Default is `False`.
        r : int
            Read quorum needed for the result. This defaults to 1, in which case the document found in the index is
            returned. If set to a higher value, each document is read from at least that many replicas before it is
            returned in the results. This is likely to take more time than using only the document stored locally with
            the index. Default is `None`.
        bookmark : str
            A string that enables you to specify which page of results you require. Used for paging through result
            sets. Every query returns an opaque string under the `bookmark` key that can then be passed back in a query
            to get the next page of results. If any part of the selector query changes between requests, the results
            are undefined. Default is `None`.
        update: bool
            Whether to update the index prior to returning the result. Default is `True`.
        stable : bool
            Whether or not the view results should be returned from a “stable” set of shards. Default is `None`.
        execution_stats : bool
            Include [execution statistics](https://docs.couchdb.org/en/main/api/database/find.html#find-statistics) in
            the query response. Default is `False`.

        Returns
        -------
        Dict: A dictionary containing the following keys.

          - dbname (`str`) – Name of database
          - index (`Dict`) – Index used to fulfill the query

The bulk document API allows you to create and update multiple documents at the same time within a single request. The basic operation is similar to creating or updating a single document, except that you batch the document structure and information.

When creating new documents the document ID (_id) is optional.

For updating existing documents, you must provide the document ID, revision information (_rev), and new document values.

In case of batch deleting documents all fields as document ID, revision information and deletion status (_deleted) are required.

Parameters

docs : List[Union[Dict, Document]]
List of documents objects
new_edits : bool
If False, prevents the database from assigning them new revision IDs. Default True.

Returns

List[Dict] : A list of dictionaries containing the following keys.

  • id the document's id
  • ok operation status
  • rev the document's revision

This method can be called to query several documents in bulk. It is well suited for fetching a specific revision of documents, as replicators do for example, or for getting revision history.

Parameters

docs : List[Union[Dict, Document]]
List of document objects, with id, and optionally rev and atts_since.
revs : bool
Give the revisions history.

Returns

List[Dict] : An array of results for each requested document/rev pair.

Shows which index is being used by the query. Parameters are the same as Database.find().

Parameters

selector : Dict
JSON object describing criteria used to select documents. More information provided in CouchDB's section on selector syntax.
limit : int
Maximum number of results returned. Default is 25.
skip : int
Skip the first n results, where n is the value specified. Default is 0.
sort : Dict
JSON array following CouchDB's [sort syntax] (https://docs.couchdb.org/en/main/api/database/find.html#find-sort). Default is None.
fields : List[str]
Dictionary specifying which fields of each object should be returned. If it is omitted, the entire object is returned. More information provided in CouchDB's [section on filtering fields] (https://docs.couchdb.org/en/main/api/database/find.html#find-filter).
use_index : Union[str, List[str]]
Instruct a query to use a specific index. Specified either as "<design_document>" or ["<design_document>", "<index_name>"]. Default is None.
conflicts : bool
Include conflicted documents if True. Intended use is to easily find conflicted documents, without an index or view. Default is False.
r : int
Read quorum needed for the result. This defaults to 1, in which case the document found in the index is returned. If set to a higher value, each document is read from at least that many replicas before it is returned in the results. This is likely to take more time than using only the document stored locally with the index. Default is None.
bookmark : str
A string that enables you to specify which page of results you require. Used for paging through result sets. Every query returns an opaque string under the bookmark key that can then be passed back in a query to get the next page of results. If any part of the selector query changes between requests, the results are undefined. Default is None.
update : bool
Whether to update the index prior to returning the result. Default is True.
stable : bool
Whether or not the view results should be returned from a “stable” set of shards. Default is None.
execution_stats : bool
Include execution statistics in the query response. Default is False.

Returns

Dict: A dictionary containing the following keys.

  • dbname (str) – Name of database
  • index (Dict) – Index used to fulfill the query
  • selector (Dict) – Query selector used
  • opts (Dict) – Query options used
  • limit (int) – Limit parameter used
  • skip (int) – Skip parameter used

Create a new index on a database.

Parameters

index : Dict
Dictionary describing the index to create.
ddoc : str
Name of the design document in which the index will be created. By default, each index will be created in its own design document. Indexes can be grouped into design documents for efficiency. However, a change to one index in a design document will invalidate all other indexes in the same document (similar to views).
name : str
Name of the index. If no name is provided, a name will be generated automatically.
index_type : str
Can be json or text. Defaults to json. Geospatial indexes will be supported in the future. Optional Text indexes are supported via a third party library
partitioned : bool
Determines whether a JSON index is partitioned or global. The default value of partitioned is the partitioned property of the database. To create a global index on a partitioned database, specify False for the "partitioned" field. If you specify True for the "partitioned" field on an unpartitioned database, an error occurs.

Returns

Tuple[str, str, str]: A tuple consisting of the following elements.

  • result (str) – Flag to show whether the index was created or one already exists. Can be "created" or "exists".
  • id (str) – Id of the design document the index was created in.

view : str
The view's id.
conflicts : bool
Include conflicts information in response. Ignored if include_docs isn’t True. Default is None.
descending : bool
Return the documents in descending order by key. Default is None.
endkey : str
Stop returning records when the specified key is reached. Default is None
endkey_docid : str
Stop returning records when the specified document ID is reached. Ignored if endkey is not set. Default is None.
group : bool
Group the results using the reduce function to a group or single row. Implies reduce is true and the maximum group_level. Default is None.
group_level : int
Specify the group level to be used. Implies group is true. Default is None.
include_docs : bool
Include the associated document with each row. Default is None.
attachments : bool
Include the Base64-encoded content of attachments in the documents that are included if include_docs is True. Ignored if include_docs isn’t True. Default is None.
att_encoding_info : bool
Include encoding information in attachment stubs if include_docs is True and the particular attachment is compressed. Ignored if include_docs isn’t True. Default is False.
inclusive_end : bool
Specifies whether the specified end key should be included in the result. Default is None.
key : str
