The doc you mentioned above is talking about setting batch size for a single machine with multiple cores. (Since the number of cores is usually power of 2.) However, doing machine learning on big data engines like Spark/Flink is a bit different from doing machine learning on a single machine --- We would have arbitary number of parallel instances. I have no preference on the default value of batch size. If you prefer using 32 as the default value, please let me know. -- This is an automated message from the Apache Git Service.
