Class ExecNodeConfig

java.lang.Object

org.apache.flink.table.planner.plan.nodes.exec.ExecNodeConfig

All Implemented Interfaces:

ReadableConfig

@Internal
public final class ExecNodeConfig
extends Object
implements ReadableConfig

Configuration view which is used combine the PlannerBase.getTableConfig() with the ExecNodeBase.getPersistedConfig() configuration. The persisted configuration of the ExecNode which is deserialized from the JSON plan has precedence over the PlannerBase.getTableConfig().

This class is intended to contain additional context information for ExecNode translation such as shouldSetUid() or helper methods for accessing configuration such as getStateRetentionTime().

get

public <T> T get(ConfigOption<T> option)

Description copied from interface: ReadableConfig

Specified by:

get in interface ReadableConfig

Type Parameters:

T - type of the value to read

Parameters:

option - metadata of the option to read

Returns:

read value or ConfigOption.defaultValue() if not found

getOptional

public <T> Optional<T> getOptional(ConfigOption<T> option)

Description copied from interface: ReadableConfig

Reads a value using the metadata included in ConfigOption. In contrast to ReadableConfig.get(ConfigOption) returns Optional.empty() if value not present.

Specified by:

getOptional in interface ReadableConfig

Type Parameters:

T - type of the value to read

Parameters:

option - metadata of the option to read

Returns:

read value or Optional.empty() if not found

ReadableConfig.get(ConfigOption)

getStateRetentionTime

public long getStateRetentionTime()

Returns:

The duration until state which was not updated will be retained.

isCompiled

public boolean isCompiled()

Returns:

Whether the ExecNode translation happens as part of a plan compilation.

shouldSetUid

public boolean shouldSetUid()

Returns:

Whether transformations should set a UID.
