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.

Method Summary

Modifier and Type	Method and Description
org.apache.flink.api.dag.Pipeline	createPipeline(List<org.apache.flink.api.dag.Transformation<?>> transformations, org.apache.flink.configuration.ReadableConfig tableConfiguration, String defaultJobName) Translates the given transformations to a Pipeline.
org.apache.flink.api.common.JobExecutionResult	execute(org.apache.flink.api.dag.Pipeline pipeline) Executes the given pipeline.
org.apache.flink.core.execution.JobClient	executeAsync(org.apache.flink.api.dag.Pipeline pipeline) Executes the given pipeline asynchronously.
org.apache.flink.configuration.ReadableConfig	getConfiguration() Gives read-only access to the configuration of the executor.
boolean	isCheckpointingEnabled() Checks whether checkpointing is enabled.

Method Detail

getConfiguration

org.apache.flink.configuration.ReadableConfig getConfiguration()

Gives read-only access to the configuration of the executor.

createPipeline

org.apache.flink.api.dag.Pipeline createPipeline(List<org.apache.flink.api.dag.Transformation<?>> transformations,
                                                 org.apache.flink.configuration.ReadableConfig tableConfiguration,
                                                 @Nullable
                                                 String defaultJobName)

Translates the given transformations to a Pipeline.

Parameters:

transformations - list of transformations

tableConfiguration - table-specific configuration options

defaultJobName - default job name if not specified via PipelineOptions.NAME

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.

isCheckpointingEnabled

boolean isCheckpointingEnabled()

Checks whether checkpointing is enabled.

Returns:

True if checkpointing is enables, false otherwise.
