    taskId

    TaskId of the FinatraTransformer being managed used for internal logging

    transformerName

    Transformer name of the FinatraTransformer being managed used for internal logging

    onWatermark

    OnWatermark callback which is called when a new watermark is emitted

    watermarkAssignor
