Abstract Value Members

  1. abstract def postMaterialization(maybeDataframe: Option[DataFrame], maybeError: Option[Throwable]): Try[Unit]

    maybeDataframe

    (optional) output dataframe of the strategy (it is None only if the strategy has no writer)

    maybeError

    Some(error) if an error happened during materialization; None otherwise

    returns

    the wanted outcome of the strategy. This means that if the maybeError is not None and the hook does not have a "recovery" logic, it should always return a Failure wrapping the input error.
