All Implemented Interfaces:: Serializable, Comparable<MuleRuntimeFeature>, Feature

public enum MuleRuntimeFeature
extends Enum<MuleRuntimeFeature>
implements Feature

List of Features that can be configured to be enabled or disabled per application depending on the deployment context.

When some Mule runtime feature needs to be flagged, it should be added here as a new enum constant. Each entry must have a meaningful name, clear enough to understand what it represents, a description with enough information to know how the runtime will work whether the feature is enabled or disabled, the issue that motivated this feature, and a list of Runtime versions from when it exists. Each enum constant has to have its Javadoc with further information about how the feature is configured.

For example:

    public enum MuleRuntimeFeature implements Feature {
      ...

      /**
       * An application shouldn't override reserved properties, but it was possible until MULE-17659. This behaviour has
       * to be fixed by default to any application developed for 4.3.0+ Runtime but can be overridden by setting
       * {@link MuleSystemProperties#HONOUR_RESERVED_PROPERTIES_PROPERTY} System Property.
       *
       * @since 4.4.0, 4.3.1
       *
       */
      HONOUR_RESERVED_PROPERTIES("Whether reserved properties such as 'app.name' can't be overridden by global properties.",
            "MULE-19083", "4.4.0, 4.3.1", HONOUR_RESERVED_PROPERTIES_PROPERTY),

      ...

    }

Since:: 4.4.0 4.3.1

Enum Constants
Enum Constant and Description
`BATCH_FIXED_AGGREGATOR_TRANSACTION_RECORD_BUFFER` If set to true, then fixed batch aggregator will only commit when a full block is processed.
`COMPUTE_CONNECTION_ERRORS_IN_STATS` If set to true, the connection errors will be taken into account to trigger alerts.
`CREATE_CHILD_POLICY_CONTEXT_FOR_PARALLEL_SCOPES` "When enabled, a new (Source) Policy Context is created for the execution of parallel scopes: ParallelForeach, ScatterGather and Async"
`DEFAULT_ERROR_HANDLER_NOT_ROLLBACK_IF_NOT_CORRESPONDING` When enabled, the default error handler added by the runtime will not rollback a transaction that should not be rollback by it
`DISABLE_SCHEDULER_LOGGING` When enabled, the Scheduler does not log exceptions.
`DW_REMOVE_SHADOWED_IMPLICIT_INPUTS` When enabled, DataWeave will remove implicit inputs when a variable with the same name is declared at the root level.
`ENABLE_BYTE_BUDDY_OBJECT_CREATION` When enabled, the Objects factories will be created with Byte Buddy instead of CGLIB.
`ENABLE_POLICY_ISOLATION` If set to true, extensions imported by a policy will be managed in complete isolation from the extensions imported by the application that is being applied to, and validations will prevent the usage of explicit configurations declared by the application as part of the policy initialization."
`ENABLE_PROFILING_SERVICE` If set to true, profiling events will be produced.
`ENABLE_XML_SDK_MDC_RESET` When enabled, the MDC context will reset after XML SDK Operation has been executed.
`ENTITY_RESOLVER_FAIL_ON_FIRST_ERROR` If set to true, the Mule XML DSL parser will fail when deploying an application that declares a schema that cannot be located.
`ERROR_AND_ROLLBACK_TX_WHEN_TIMEOUT` When enabled, when a (local or xa) transaction reached timeout, an error will be thrown that can be handled using error handling.
`FORCE_RUNTIME_PROFILING_CONSUMERS_ENABLEMENT`
`FORK_JOIN_COMPLETE_CHILDREN_ON_TIMEOUT`
`HANDLE_SPLITTER_EXCEPTION` If set to true, then DW will correctly handle Splitter's exceptions, avoiding some serialization issues.
`HONOUR_ERROR_MAPPINGS_WHEN_POLICY_APPLIED_ON_OPERATION` When set to true, the operation policy's error resolution is ignored so that the error mappings of the processor on which the policy was applied are set successfully
`HONOUR_INSECURE_TLS_CONFIGURATION` When enabled, the insecure attribute of the trust-store element will be honoured even when other attributes are configured.
`HONOUR_PERSISTED_FLOW_STATE` When enabled, flows will honour the state configured in flows.deployment.properties when restarting the app, regardless of the initial state.
`HONOUR_RESERVED_PROPERTIES` An application shouldn't override reserved properties, but it was possible until MULE-17659.
`MULE_PRINT_DETAILED_COMPOSITE_EXCEPTION_LOG` When enabled, AbstractForkJoinRouter based processors, such as ParallelForEach and ScatterGather routers, will show detailed error information for their failed routes.
`PARALLEL_FOREACH_FLATTEN_MESSAGE` When enabled, if the items to iterate over on a parallel-foreach scope are messages (such as the output of an operation that returns Result objects), they will be flattened in a way that is consistent with what the foreach scope does.
`RETHROW_EXCEPTIONS_IN_IDEMPOTENT_MESSAGE_VALIDATOR` When enabled, internal exceptions when processing an event in the 'idempotent-message-validator' will be rethrown instead of raising a general MULE:DUPLICATE_MESSAGE.
`SET_VARIABLE_WITH_NULL_VALUE`
`START_EXTENSION_COMPONENTS_WITH_ARTIFACT_CLASSLOADER` If set to true, extensions will only be able to load exported resources from the deployable artifacts (application, policy, domain).
`SUPPORT_NATIVE_LIBRARY_DEPENDENCIES` When enabled, and the application needs to load a native library, the rest of the native libraries are preloaded in the application's Classloader.
`SUPPRESS_ERRORS` When enabled, error suppression will happen.
`TO_STRING_TRANSFORMER_TRANSFORM_ITERATOR_ELEMENTS` If set to true, managed iterators transformed to Strings will show the representation of the elements instead of the generic 'org.mule.runtime.core.internal.streaming.object.ManagedCursorIteratorProvider$ManagedCursorIterator@######'.
`USE_TRANSACTION_SINK_INDEX` When enabled, flux sinks will be cached using index as part of the key.

    Returns:
    
    The feature description
  - getIssueId
```
public String getIssueId()

  - getOverridingSystemPropertyName
```
public Optional<String> getOverridingSystemPropertyName()
```
    Description copied from interface: Feature
    System Property name to be used to decide whether the feature has to be enabled or disabled for the whole Runtime instance without considering any other condition related to the deployment context. The feature will be enabled according to the value provided, by parsing it as a boolean.
    
    For instance if Feature.getOverridingSystemPropertyName():
    1. Is set to a non-null value and there is a System Property defined with this name, then the feature will be enabled or disabled depending on the result of parse the property value.
    2. Is not set or there isn't a System Property defined with a the value assigned to it, then the proper feature flagging criteria will be applied according to how it was configured.
    In other words:
    1. If Feature.getOverridingSystemPropertyName() is set to some.meaningful.name
      
      If the System Property was set (System.getProperty("some.meaningful.name">) is not null), then the feature will be enabled only when Boolean.getBoolean("some.meaningful.name") returns true
      
      If the System Property was not set (System.getProperty("some.meaningful.name">) is null), then the feature flagging configuration will be applied to decide whether the feature is enabled or disabled.
    2. If Feature.getOverridingSystemPropertyName() is not set, then the feature flagging configuration will be applied to decide whether the feature is enabled or disabled.
    Specified by:
    
    getOverridingSystemPropertyName in interface Feature
    
    Returns:
    
    The name of a System Property to configure the feature.
