org.apache.flink.table.delegation

Interface Executor

@Internal
public interface Executor

It enables execution of a Transformations graph generated by Planner.

This uncouples the TableEnvironment from any given runtime.

Method Detail

createPipeline

org.apache.flink.api.dag.Pipeline createPipeline(List<org.apache.flink.api.dag.Transformation<?>> transformations,
                                                 TableConfig tableConfig,
                                                 String jobName)

Translates the given transformations to a Pipeline.

Parameters:

transformations - list of transformations

jobName - what should be the name of the job

Returns:

The pipeline representing the transformations.

execute

org.apache.flink.api.common.JobExecutionResult execute(org.apache.flink.api.dag.Pipeline pipeline)
                                                throws Exception

Executes the given pipeline.

Parameters:

pipeline - the pipeline to execute

Returns:

The result of the job execution, containing elapsed time and accumulators.

Throws:

Exception - which occurs during job execution.

executeAsync

org.apache.flink.core.execution.JobClient executeAsync(org.apache.flink.api.dag.Pipeline pipeline)
                                                throws Exception

Executes the given pipeline asynchronously.

Parameters:

pipeline - the pipeline to execute

Returns:

A JobClient that can be used to communicate with the submitted job, completed on submission succeeded.

Throws:

Exception - which occurs during job execution.
