All Implemented Interfaces:

Executor, ExecutorService, DistributedExecutorService

public class DefaultExecutorService
extends AbstractExecutorService
implements DistributedExecutorService

Deprecated.

since 9.1 Please use EmbeddedCacheManager.executor() or CacheStream instead.

Infinispan's implementation of an ExecutorService and DistributedExecutorService. This ExecutorService provides methods to submit tasks for an execution on a cluster of Infinispan nodes.

Note that due to potential task migration to another nodes every Callable, Runnable and/or DistributedCallable submitted must be either Serializable or Externalizable. Also the value returned from a callable must be Serializable or Externalizable. Unfortunately if the value returned is not serializable then a NotSerializableException will be thrown.

Since:

5.0

Constructor Detail

DefaultExecutorService

public DefaultExecutorService(Cache<?,?> masterCacheNode)

Deprecated.

Creates a new DefaultExecutorService given a master cache node for local task execution. All distributed task executions will be initiated from this Infinispan cache node

Parameters:

masterCacheNode - Cache node initiating distributed task

DefaultExecutorService

public DefaultExecutorService(Cache<?,?> masterCacheNode,
                              ExecutorService localExecutorService)

Deprecated.

Creates a new DefaultExecutorService given a master cache node and an ExecutorService for parallel execution of tasks ran on this node. All distributed task executions will be initiated from this Infinispan cache node.

Note that DefaultExecutorService will not shutdown client supplied localExecutorService once this DefaultExecutorService is shutdown. Lifecycle management of a supplied ExecutorService is left to the client Also note that client supplied ExecutorService should not execute tasks in the caller's thread ( i.e rejectionHandler of ThreadPoolExecutor configured with {link ThreadPoolExecutor.CallerRunsPolicy)

Parameters:

masterCacheNode - Cache node initiating distributed task

localExecutorService - ExecutorService to run local tasks

DefaultExecutorService

public DefaultExecutorService(Cache<?,?> masterCacheNode,
                              ExecutorService localExecutorService,

Deprecated.

Creates a new DefaultExecutorService given a master cache node and an ExecutorService for parallel execution of task ran on this node. All distributed task executions will be initiated from this Infinispan cache node.

Parameters:

masterCacheNode - Cache node initiating distributed task

localExecutorService - ExecutorService to run local tasks

takeExecutorOwnership - if true ExecutorService.shutdown() and ExecutorService.shutdownNow() method will shutdown localExecutorService as well
