ExecutionConfig (Flink : 1.12-SNAPSHOT API)

java.lang.Object
- org.apache.flink.api.common.ExecutionConfig

All Implemented Interfaces:

Serializable, Archiveable<ArchivedExecutionConfig>
```
@Public
public class ExecutionConfig
extends Object
implements Serializable, Archiveable<ArchivedExecutionConfig>
```
A config to define the behavior of the program execution. It allows to define (among other options) the following settings:
- The default parallelism of the program, i.e., how many parallel tasks to use for all functions that do not define a specific value directly.
- The number of retries in the case of failed executions.
- The delay between execution retries.
- The ExecutionMode of the program: Batch or Pipelined. The default execution mode is ExecutionMode.PIPELINED
- Enabling or disabling the "closure cleaner". The closure cleaner pre-processes the implementations of functions. In case they are (anonymous) inner classes, it removes unused references to the enclosing class to fix certain serialization-related problems and to reduce the size of the closure.
- The config allows to register types and serializers to increase the efficiency of handling generic types and POJOs. This is usually only needed when the functions return not only the types declared in their signature, but also subclasses of those types.

  - enableClosureCleaner
```
public ExecutionConfig enableClosureCleaner()
```
    Enables the ClosureCleaner. This analyzes user code functions and sets fields to null that are not used. This will in most cases make closures or anonymous inner classes serializable that where not serializable due to some Scala or Java implementation artifact. User code must be serializable because it needs to be sent to worker nodes.
  - disableClosureCleaner

    Disables the ClosureCleaner.
    
    See Also:
    
    enableClosureCleaner()

public ExecutionConfig.ClosureCleanerLevel getClosureCleanerLevel()
```
    Returns the configured ExecutionConfig.ClosureCleanerLevel.
  - setAutoWatermarkInterval
```
@PublicEvolving
public ExecutionConfig setAutoWatermarkInterval(long interval)
```
    Sets the interval of the automatic watermark emission. Watermarks are used throughout the streaming system to keep track of the progress of time. They are used, for example, for time based windowing.
    Setting an interval of 0 will disable periodic watermark emission.
    
    Parameters:
    
    interval - The interval between watermarks in milliseconds.
  - getAutoWatermarkInterval
```
@PublicEvolving
public long getAutoWatermarkInterval()
```
    Returns the interval of the automatic watermark emission.
    
    See Also:
    
    setAutoWatermarkInterval(long)
  - setLatencyTrackingInterval
```
@PublicEvolving
public ExecutionConfig setLatencyTrackingInterval(long interval)
```
    Interval for sending latency tracking marks from the sources to the sinks. Flink will send latency tracking marks from the sources at the specified interval.
    Setting a tracking interval <= 0 disables the latency tracking.
    
    Parameters:
    
    interval - Interval in milliseconds.
  - getLatencyTrackingInterval
```
@PublicEvolving
public long getLatencyTrackingInterval()
```
    Returns the latency tracking interval.
    
    Returns:
    
    The latency tracking interval in milliseconds
  - isLatencyTrackingConfigured
```
@Internal
public boolean isLatencyTrackingConfigured()
```
  - getParallelism
```
public int getParallelism()
```
    Gets the parallelism with which operation are executed by default. Operations can individually override this value to use a specific parallelism.
    Other operations may need to run with a different parallelism - for example calling a reduce operation over the entire data set will involve an operation that runs with a parallelism of one (the final reduce to the single result value).
    
    Returns:
    
    The parallelism used by operations, unless they override that value. This method returns PARALLELISM_DEFAULT if the environment's default parallelism should be used.
  - setParallelism
```
public ExecutionConfig setParallelism(int parallelism)
```
    Sets the parallelism for operations executed through this environment. Setting a parallelism of x here will cause all operators (such as join, map, reduce) to run with x parallel instances.
    This method overrides the default parallelism for this environment. The local execution environment uses by default a value equal to the number of hardware contexts (CPU cores / threads). When executing the program via the command line client from a JAR file, the default parallelism is the one configured for that setup.
    
    Parameters:
    
    parallelism - The parallelism to use
  - getMaxParallelism
```
@PublicEvolving
public int getMaxParallelism()
```
    Gets the maximum degree of parallelism defined for the program.
    The maximum degree of parallelism specifies the upper limit for dynamic scaling. It also defines the number of key groups used for partitioned state.
    
    Returns:
    
    Maximum degree of parallelism
  - setMaxParallelism
```
@PublicEvolving
public void setMaxParallelism(int maxParallelism)
```
    Sets the maximum degree of parallelism defined for the program.
    The maximum degree of parallelism specifies the upper limit for dynamic scaling. It also defines the number of key groups used for partitioned state.
    
    Parameters:
    
    maxParallelism - Maximum degree of parallelism to be used for the program.
  - getTaskCancellationInterval
```
public long getTaskCancellationInterval()
```
    Gets the interval (in milliseconds) between consecutive attempts to cancel a running task.
  - setTaskCancellationInterval
```
public ExecutionConfig setTaskCancellationInterval(long interval)
```
    Sets the configuration parameter specifying the interval (in milliseconds) between consecutive attempts to cancel a running task.
    
    Parameters:
    
    interval - the interval (in milliseconds).
  - getTaskCancellationTimeout
```
@PublicEvolving
public long getTaskCancellationTimeout()
```
    Returns the timeout (in milliseconds) after which an ongoing task cancellation leads to a fatal TaskManager error.
    The value 0 means that the timeout is disabled. In this case a stuck cancellation will not lead to a fatal error.
  - setTaskCancellationTimeout
```
@PublicEvolving
public ExecutionConfig setTaskCancellationTimeout(long timeout)
```
    Sets the timeout (in milliseconds) after which an ongoing task cancellation is considered failed, leading to a fatal TaskManager error.
    The cluster default is configured via TaskManagerOptions.TASK_CANCELLATION_TIMEOUT.
    The value 0 disables the timeout. In this case a stuck cancellation will not lead to a fatal error.
    
    Parameters:
    
    timeout - The task cancellation timeout (in milliseconds).
  - setRestartStrategy
```
@PublicEvolving
public void setRestartStrategy(RestartStrategies.RestartStrategyConfiguration restartStrategyConfiguration)

  - enableForceKryo
```
public void enableForceKryo()
```
    Force TypeExtractor to use Kryo serializer for POJOS even though we could analyze as POJO. In some cases this might be preferable. For example, when using interfaces with subclasses that cannot be analyzed as POJO.
  - disableForceKryo
```
public void disableForceKryo()
```
    Disable use of Kryo serializer for all POJOs.
  - isForceKryoEnabled
```
public boolean isForceKryoEnabled()
```
  - enableGenericTypes
```
public void enableGenericTypes()
```
    Enables the use generic types which are serialized via Kryo.
    Generic types are enabled by default.
    
    See Also:
    
    disableGenericTypes()
  - disableGenericTypes
```
public void disableGenericTypes()
```
    Disables the use of generic types (types that would be serialized via Kryo). If this option is used, Flink will throw an UnsupportedOperationException whenever it encounters a data type that would go through Kryo for serialization.
    Disabling generic types can be helpful to eagerly find and eliminate the use of types that would go through Kryo serialization during runtime. Rather than checking types individually, using this option will throw exceptions eagerly in the places where generic types are used.
    Important: We recommend to use this option only during development and pre-production phases, not during actual production use. The application program and/or the input data may be such that new, previously unseen, types occur at some point. In that case, setting this option would cause the program to fail.
    
    See Also:
    
    enableGenericTypes()
  - hasGenericTypesDisabled
```
public boolean hasGenericTypesDisabled()
```
    Checks whether generic types are supported. Generic types are types that go through Kryo during serialization.
    Generic types are enabled by default.
    
    See Also:
    
    enableGenericTypes(), disableGenericTypes()
  - enableAutoGeneratedUIDs
```
public void enableAutoGeneratedUIDs()
```
    Enables the Flink runtime to auto-generate UID's for operators.
    
    See Also:
    
    disableAutoGeneratedUIDs()
  - disableAutoGeneratedUIDs
```
public void disableAutoGeneratedUIDs()
```
    Disables auto-generated UIDs. Forces users to manually specify UIDs on DataStream applications.
    It is highly recommended that users specify UIDs before deploying to production since they are used to match state in savepoints to operators in a job. Because auto-generated ID's are likely to change when modifying a job, specifying custom IDs allow an application to evolve overtime without discarding state.
  - hasAutoGeneratedUIDsEnabled
```
public boolean hasAutoGeneratedUIDsEnabled()
```
    Checks whether auto generated UIDs are supported.
    Auto generated UIDs are enabled by default.
    
    See Also:
    
    enableAutoGeneratedUIDs(), disableAutoGeneratedUIDs()
  - enableForceAvro

    Important: Make sure to include the flink-avro module.
  - disableForceAvro
```
public void disableForceAvro()
```
    Disables the Apache Avro serializer as the forced serializer for POJOs.
  - isForceAvroEnabled
```
public boolean isForceAvroEnabled()
```
    Returns whether the Apache Avro is the default serializer for POJOs.
  - enableObjectReuse
```
public ExecutionConfig enableObjectReuse()
```
    Enables reusing objects that Flink internally uses for deserialization and passing data to user-code functions. Keep in mind that this can lead to bugs when the user-code function of an operation is not aware of this behaviour.
  - disableObjectReuse
```
public ExecutionConfig disableObjectReuse()
```
    Disables reusing objects that Flink internally uses for deserialization and passing data to user-code functions. @see #enableObjectReuse()
