translateToPlanInternal

                                                                                                               ExecNodeConfig config)

从类复制的说明: ExecNodeBase

Internal method, translates this node into a Flink operator.

覆盖:

translateToPlanInternal 在类中 CommonExecTableSourceScan

参数:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.

从类复制的说明: CommonExecTableSourceScan

Creates a Transformation based on the given InputFormat. The implementation is different for streaming mode and batch mode.
