 # This is the default collection properties for Weaviate.
 # It's a list of properties that will be created on the collection.
 # These are extremely similar to the Document dataclass, but with a few differences:
 # - `id` is renamed to `_original_id` as the `id` field is reserved by Weaviate.
 # - `blob` is split into `blob_data` and `blob_mime_type` as it's more efficient to store them separately.
 # Blob meta is missing as it's not usually serialized when saving a Document as we rely on the Document own meta.
 #
 # Also the Document `meta` fields are omitted as we can't make assumptions on the structure of the meta field.
 # We recommend the user to create a proper collection with the correct meta properties for their use case.
 # We mostly rely on these defaults for testing purposes using Weaviate automatic schema generation, but that's not
 # recommended for production use.

    WeaviateDocumentStore is a Document Store for Weaviate.
    It can be used with Weaviate Cloud Services or self-hosted instances.
    Usage example with Weaviate Cloud Services:
    ```python
    import os
    from haystack_integrations.document_stores.weaviate.auth import AuthApiKey
    from haystack_integrations.document_stores.weaviate.document_store import WeaviateDocumentStore
    os.environ["WEAVIATE_API_KEY"] = "MY_API_KEY
    document_store = WeaviateDocumentStore(
        url="rAnD0mD1g1t5.something.weaviate.cloud",
        auth_client_secret=AuthApiKey(),
    )
    ```
    Usage example with self-hosted Weaviate:
    ```python
    from haystack_integrations.document_stores.weaviate.document_store import WeaviateDocumentStore
    document_store = WeaviateDocumentStore(url="http://localhost:8080")
    ```

        Create a new instance of WeaviateDocumentStore and connects to the Weaviate instance.
        :param url:
            The URL to the weaviate instance.
        :param collection_settings:
            The collection settings to use. If `None`, it will use a collection named `default` with the following
            properties:
            - _original_id: text
            - content: text
            - dataframe: text
            - blob_data: blob
            - blob_mime_type: text

            The Document `meta` fields are omitted in the default collection settings as we can't make assumptions
            on the structure of the meta field.
            We heavily recommend to create a custom collection with the correct meta properties
            for your use case.
            Another option is relying on the automatic schema generation, but that's not recommended for
            production use.
            See the official `Weaviate documentation<https://weaviate.io/developers/weaviate/manage-data/collections>`_
            for more information on collections and their properties.
        :param auth_client_secret:
            Authentication credentials. Can be one of the following types depending on the authentication mode:
            - `AuthBearerToken` to use existing access and (optionally, but recommended) refresh tokens
            - `AuthClientPassword` to use username and password for oidc Resource Owner Password flow
            - `AuthClientCredentials` to use a client secret for oidc client credential flow
            - `AuthApiKey` to use an API key
        :param additional_headers:
            Additional headers to include in the requests. Can be used to set OpenAI/HuggingFace keys.
            OpenAI/HuggingFace key looks like this:
            ```
            {"X-OpenAI-Api-Key": "<THE-KEY>"}, {"X-HuggingFace-Api-Key": "<THE-KEY>"}
            ```
        :param embedded_options:
