+ InferMode |
+ An option for selecting the hive source parallelism inference mode to infer parallelism according to splits number.
+ 'static' represents static inference, which will infer source parallelism at job create stage.
+ 'dynamic' represents dynamic inference, which will infer parallelism at job execution stage and could more accurately infer the source parallelism.
+ 'none' represents disabling parallelism inference.
+ Note that it is still affected by the deprecated option 'table.exec.hive.infer-source-parallelism', requiring its value to be true for enabling parallelism inference.
