Package org.apache.flink.table.delegation

Interface Executor

@Internal public interface Executor
It enables the execution of a graph of Transformations generated by the Planner.

This uncouples the TableEnvironment from any given runtime.

Note that not every table program calls createPipeline(List, ReadableConfig, String) or execute(Pipeline). When bridging to DataStream API, this interface serves as a communication layer to the final pipeline executor via StreamExecutionEnvironment.
