Interface StatementSet

All Superinterfaces:

Compilable, Executable, Explainable<StatementSet>

All Known Implementing Classes:

StatementSetImpl

@PublicEvolving
public interface StatementSet
extends Explainable<StatementSet>, Compilable, Executable

A StatementSet accepts pipelines defined by DML statements or Table objects. The planner can optimize all added statements together and then submit them as one job.

The added statements will be cleared when calling the execute() method.

Method Summary

StatementSet	addInsert(TableDescriptor targetDescriptor, Table table) Shorthand for statementSet.add(table.insertInto(targetDescriptor)).
StatementSet	addInsert(TableDescriptor targetDescriptor, Table table, boolean overwrite) Shorthand for statementSet.add(table.insertInto(targetDescriptor, overwrite)).
StatementSet	addInsertSql(String statement) Adds an INSERT INTO SQL statement.

Method Detail

add

StatementSet add(TablePipeline tablePipeline)

Adds a TablePipeline.

addInsertSql

StatementSet addInsertSql(String statement)

Adds an INSERT INTO SQL statement.

addInsert

StatementSet addInsert(String targetPath,
                       Table table)

Shorthand for statementSet.add(table.insertInto(targetPath)).

add(TablePipeline), Table.insertInto(String)

addInsert

StatementSet addInsert(String targetPath,
                       Table table,
                       boolean overwrite)

Shorthand for statementSet.add(table.insertInto(targetPath, overwrite)).

See Also:

add(TablePipeline), Table.insertInto(String, boolean)

addInsert

StatementSet addInsert(TableDescriptor targetDescriptor,
                       Table table)

Shorthand for statementSet.add(table.insertInto(targetDescriptor)).

See Also:

add(TablePipeline), Table.insertInto(TableDescriptor)

addInsert

StatementSet addInsert(TableDescriptor targetDescriptor,
                       Table table,
                       boolean overwrite)

Shorthand for statementSet.add(table.insertInto(targetDescriptor, overwrite)).

See Also:

add(TablePipeline), Table.insertInto(TableDescriptor, boolean)

execute

TableResult execute()

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

compilePlan

@Experimental
CompiledPlan compilePlan()
                                throws org.apache.flink.table.api.TableException

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

Throws:

TableException - if any of the statements is invalid or if the plan cannot be persisted.
