接口摘要

WorkerComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerComputable defines worker computation for any guagua application.
WorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerInterceptor defines hook points for each guagua application.

类摘要

AbstractCombineWorkerComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable,KEY extends Bytable,VALUE extends Bytable>	A high-effective implementation to load data and do computation.
AbstractWorkerComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable,KEY extends Bytable,VALUE extends Bytable>	Abstract WorkerComputable implementation to load data one by one and only in the very 1st iteration.
AbstractWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AbstractWorkerCoordinator has some common implementation for both async and sync worker coordinator.
AsyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AsyncWorkerCoordinator is used to as a worker barrier for each iteration.
BasicWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	Empty WorkerInterceptor implementation for user to choose which function should be override.
GuaguaWorkerService<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	GuaguaWorkerService is the basic implementation as a worker for whole application process.
LocalWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	LocalWorkerCoordinator is local coordinator implementation in one jvm instance.
MemoryStatsWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MemoryStatsWorkerInterceptor is used to print memory usage for each worker checkpoint.
SyncWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	SyncWorkerCoordinator is used to as a worker barrier for each iteration.
TraceWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	TraceWorkerInterceptor is used to trace whole application process.
WorkerComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerComputableTimer is used to print execution time for master computation function.
WorkerContext<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	WorkerContext is a context to contain all useful info which can be used in worker computation.
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.
