explain

public String explain(ExplainDetail... extraDetails)

Description copied from interface: Explainable

Returns the AST of this object and the execution plan to compute the result of the given statement.

Specified by:

explain in interface Explainable<StatementSet>

Parameters:

extraDetails - The extra explain details which the result of this method should include, e.g. estimated cost, changelog mode for streaming

Returns:

AST and the execution plan.

execute

public TableResult execute()

Description copied from interface: StatementSet

Executes this object.

By default, all DML operations are executed asynchronously. Use TableResult.await() or TableResult.getJobClient() to monitor the execution. Set TableConfigOptions.TABLE_DML_SYNC for always synchronous execution.

This method executes all statements as one job.

The added statements will be cleared after calling this method.

Specified by:

execute in interface Executable

Specified by:

execute in interface StatementSet

compilePlan

@Experimental
public CompiledPlan compilePlan()

Description copied from interface: StatementSet

Compiles this object into a CompiledPlan that can be executed as one job.

Compiled plans can be persisted and reloaded across Flink versions. They describe static pipelines to ensure backwards compatibility and enable stateful streaming job upgrades. See CompiledPlan and the website documentation for more information.

Note: The compiled plan feature is not supported in batch mode.

This method compiles all statements into a CompiledPlan that can be executed as one job.

Specified by:

compilePlan in interface Compilable

Specified by:

compilePlan in interface StatementSet
