.. py:class:: DynamoDBToS3Operator(*, dynamodb_table_name, s3_bucket_name, file_size, dynamodb_scan_kwargs = None, s3_key_prefix = '', process_func = _convert_item_to_json_bytes, aws_conn_id = 'aws_default', **kwargs)

   Bases: :py:obj:`airflow.models.BaseOperator`

   Replicates records from a DynamoDB table to S3.
   It scans a DynamoDB table and writes the received records to a file
   on the local filesystem. It flushes the file to S3 once the file size
   exceeds the file size limit specified by the user.

   Users can also specify a filtering criteria using dynamodb_scan_kwargs
   to only replicate records that satisfy the criteria.

   .. seealso::
       For more information on how to use this operator, take a look at the guide:
       :ref:`howto/transfer:DynamoDBToS3Operator`

   :param dynamodb_table_name: Dynamodb table to replicate data from
   :param s3_bucket_name: S3 bucket to replicate data to
   :param file_size: Flush file to s3 if file size >= file_size
   :param dynamodb_scan_kwargs: kwargs pass to <https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/dynamodb.html#DynamoDB.Table.scan>  # noqa: E501
   :param s3_key_prefix: Prefix of s3 object key
   :param process_func: How we transforms a dynamodb item to bytes. By default we dump the json
   :param aws_conn_id: The Airflow connection used for AWS credentials.
       If this is None or empty then the default boto3 behaviour is used. If
       running Airflow in a distributed manner and aws_conn_id is None or
       empty, then default boto3 configuration would be used (and must be
       maintained on each worker node).

   .. py:method:: execute(self, context)

      This is the main method to derive when creating an operator.
      Context is the same dictionary used as when rendering jinja templates.

      Refer to get_template_context for more context.
