  4. def addBatch(batchId: Long, data: DataFrame): Unit

    Permalink

    Adds a batch of data to this sink.

    Adds a batch of data to this sink. The data for a given batchId is deterministic and if this method is called more than once with the same batchId (which will happen in the case of failures), then data should only be added once.

    Note 1: You cannot apply any operators on data except consuming it (e.g., collect/foreach). Otherwise, you may get a wrong result.

    Note 2: The method is supposed to be executed synchronously, i.e. the method should only return after data is consumed by sink successfully.
