java.lang.Record

com.opencqrs.framework.eventhandler.EventHandlingProperties.ProcessorSettings.LifeCycle

Record Components:

autoStart - Whether the event handling processor shall be started automatically.

controller - The built-in life-cycle controller to use, unless "controller-registration" is specified. Defaults to "leader-election", if a unique "lock-registry" bean is available within the application context, "application-context" otherwise.

controllerRegistration - Custom EventHandlingProcessorLifecycleRegistration bean reference to use.

lockRegistry - Custom lock registry to use, if "leader-election" applies.

partitions - The number of parallel instances (partitions) to start for this event processor. It is important to note, that partitioning of EventHandlingProcessors cannot be changed later, unless the processor is completely transient, i.e. it's side-effects are completely idempotent and no persistent progress tracking is needed. In all other cases, starting a partitioned processor results in partitioned EventHandlingProperties.ProcessorSettings.Progress and parallel processing will proceed the progress independently according to the configured EventHandlingProperties.ProcessorSettings.Sequencing. Hence, reducing or increasing the number of partitions must only be performed administratively, while all instances are stopped and have the same progress. Furthermore, persistent progress needs to be duplicated for new partitions, manually.

Enclosing class:

EventHandlingProperties.ProcessorSettings

public static record EventHandlingProperties.ProcessorSettings.LifeCycle(Boolean autoStart, EventHandlingProperties.ProcessorSettings.LifeCycle.Controller controller, String controllerRegistration, String lockRegistry, Long partitions)

Constructor Details

LifeCycle

public LifeCycle(Boolean autoStart,
 EventHandlingProperties.ProcessorSettings.LifeCycle.Controller controller,
 String controllerRegistration,
 String lockRegistry,
 Long partitions)

Creates an instance of a LifeCycle record class.

Parameters:

autoStart - the value for the autoStart record component

controller - the value for the controller record component

controllerRegistration - the value for the controllerRegistration record component

lockRegistry - the value for the lockRegistry record component

partitions - the value for the partitions record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

autoStart

public Boolean autoStart()

Returns the value of the autoStart record component.

Returns:

the value of the autoStart record component

controller

public EventHandlingProperties.ProcessorSettings.LifeCycle.Controller controller()

Returns the value of the controller record component.

Returns:

the value of the controller record component

controllerRegistration

public String controllerRegistration()

Returns the value of the controllerRegistration record component.

Returns:

the value of the controllerRegistration record component

lockRegistry

public String lockRegistry()

Returns the value of the lockRegistry record component.

Returns:

the value of the lockRegistry record component

partitions

public Long partitions()

Returns the value of the partitions record component.

Returns:

the value of the partitions record component
