Document Loader for Apache Cassandra.

Args:
    table: The table to load the data from.
        (do not use together with the query parameter)
    session: The cassandra driver session.
        If not provided, the cassio resolved session will be used.
    keyspace: The keyspace of the table.
        If not provided, the cassio resolved keyspace will be used.
    query: The query used to load the data.
        (do not use together with the table parameter)
    page_content_mapper: a function to convert a row to string page content.
        Defaults to the str representation of the row.
    metadata_mapper: a function to convert a row to document metadata.
    query_parameters: The query parameters used when calling session.execute .
    query_timeout: The query timeout used when calling session.execute .
    query_trace: Whether to use tracing when calling session.execute .
    query_custom_payload: The query custom_payload used when calling
        session.execute .
    query_execution_profile: The query execution_profile used when calling
        session.execute .
    query_host: The query host used when calling session.execute .
    query_execute_as: The query execute_as used when calling session.execute .
