接口摘要

MasterComputable<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MasterComputable defines master computation for any guagua application.
MasterInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MasterInterceptor defines hook points for each guagua application.

类摘要

AbstractMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AbstractMasterCoordinator has some common implementation for both async and sync worker coordinator.
AsyncMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	AsyncMasterCoordinator is used to as a barrier for each iteration.
BasicMasterInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	Empty MasterInterceptor implementation for user to choose which function should be override.
GuaguaMasterService<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	GuaguaMasterService is the basic implementation as a master for whole guagua application process.
LocalMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	LocalMasterCoordinator is local coordinator implementation in one jvm instance.
MasterComputableTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MasterComputableTimer is used to print execution time for master computation.
MasterContext<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MasterContext is a context object which contains all useful info used in master computation.
MasterTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MasterTimer is used to log execution time of preXXXX of interceptors, master computation and postXXXX of interceptors.
MemoryStatsMasterInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	MemoryStatsMasterInterceptor is used to print memory usage for each master checkpoint.
SyncMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	SyncMasterCoordinator is used to as a barrier for each iteration.
TraceMasterInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>	TraceMasterInterceptor is used to trace whole application for master.
