    Description

      FLINK-12801 has introduce parallelism setting for table, but because TableSource generate DataStream, maybe DataStream is not a real source, that will lead to some shuffle errors. So FLINK-13494 remove these implementations.

      In this ticket, I would like to introduce parallelism inference only for InputFormatTableSource, the RowCount of InputFormatTableSource is more accurate than downstream stages. It is worth to automatically generate its parallelism.
