------------------------------------
Summary: Introduce parallelism inference for InputFormatTableSource
Key: FLINK-14676
URL: https://issues.apache.org/jira/browse/FLINK-14676
Project: Flink
Issue Type: New Feature
Components: Table SQL / Planner
Reporter: Jingsong Lee
Fix For: 1.10.0
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.
