You need to install `hippo-api` and run Hippo. Please visit our official website for how to run a Hippo instance: https://www.transwarp.cn/starwarp Args: embedding_function (Embeddings): Function used to embed the text. table_name (str): Which Hippo table to use. Defaults to "test". database_name (str): Which Hippo database to use. Defaults to "default". number_of_shards (int): The number of shards for the Hippo table.Defaults to 1. number_of_replicas (int): The number of replicas for the Hippo table.Defaults to 1. connection_args (Optional[dict[str, any]]): The connection args used for this class comes in the form of a dict. index_params (Optional[dict]): Which index params to use. Defaults to IVF_FLAT. drop_old (Optional[bool]): Whether to drop the current collection. Defaults to False. primary_field (str): Name of the primary key field. Defaults to "pk". text_field (str): Name of the text field. Defaults to "text". vector_field (str): Name of the vector field. Defaults to "vector". The connection args used for this class comes in the form of a dict, here are a few of the options: host (str): The host of Hippo instance. Default at "localhost". port (str/int): The port of Hippo instance. Default at 7788. user (str): Use which user to connect to Hippo instance. If user and password are provided, we will add related header in every RPC call. password (str): Required when user is provided. The password corresponding to the user.
