Review comment: To add to this discussion. Some of the summaries used by Tensorflow for example, is meant to be used by Tensorboard - which understands the format of the summary in order to plot visualization via [protobuf](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/framework/summary.proto), same thing with [tf.Event](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/util/event.proto). If this is the case, is there an existing discussion regarding what needs to be done in terms of the public APIs of a `Summary` class should have in Flink-ML? I haven't follow up closely with the ML but I cant find any in the [FLIP-39 documentation](https://cwiki.apache.org/confluence/display/FLINK/FLIP-39+Flink+ML+pipeline+and+ML+libs) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
