translateToPlanInternal

protected Transformation<RowData> translateToPlanInternal(org.apache.flink.table.planner.delegation.PlannerBase planner,

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Overrides:

translateToPlanInternal in class CommonExecTableSourceScan

Parameters:

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.
