False if you want them to be left in the same format as they were in Salesforce. Leaving the value as False will result in datetimes being strings. Default: False :param record_time_added: True if you want to add a Unix timestamp field to the resulting data that marks when the data was fetched from Salesforce. Default: False :param aws_conn_id: The name of the connection that has the parameters we need to connect to S3. :param replace: A flag to decide whether or not to overwrite the S3 key if it already exists. If set to False and the key exists an error will be raised. :param encrypt: If True, the file will be encrypted on the server-side by S3 and will be stored in an encrypted form while at rest in S3. :param gzip: If True, the file will be compressed locally. :param acl_policy: String specifying the canned ACL policy for the file being uploaded to the S3 bucket.
