接口 ml.shifu.guagua.worker.WorkerInterceptor
的使用

使用 WorkerInterceptor 的软件包

ml.shifu.guagua	This package contains some common classes for both master and worker.
ml.shifu.guagua.worker	This package contains guagua worker implementation.

ml.shifu.guagua 中 WorkerInterceptor 的使用

返回 WorkerInterceptor 的 ml.shifu.guagua 中的方法

WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>	SyncCoordinatorFactory.createWorkerCoordinator()
WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>	CoordinatorFactory.createWorkerCoordinator() Create coordinator instance for worker.
WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>	AsyncCoordinatorFactory.createWorkerCoordinator()

ml.shifu.guagua.worker 中 WorkerInterceptor 的使用

实现 WorkerInterceptor 的 ml.shifu.guagua.worker 中的类

class	AbstractWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> AbstractWorkerCoordinator has some common implementation for both async and sync worker coordinator.
class	AsyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> AsyncWorkerCoordinator is used to as a worker barrier for each iteration.
class	BasicWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> Empty WorkerInterceptor implementation for user to choose which function should be override.
class	LocalWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> LocalWorkerCoordinator is local coordinator implementation in one jvm instance.
class	MemoryStatsWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> MemoryStatsWorkerInterceptor is used to print memory usage for each worker checkpoint.
class	NettyWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> Worker coordinator coordinates master with Netty client channel.
class	SyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> SyncWorkerCoordinator is used to as a worker barrier for each iteration.
class	TraceWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> TraceWorkerInterceptor is used to trace whole application process.
class	WorkerComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> WorkerComputableTimer is used to print execution time for master computation function.
class	WorkerTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable> WorkerTimer is used to log execution time of preXXXX of interceptors, worker computation and postXXXX of interceptors.
