方法详细资料

canRestart

public boolean canRestart()

从接口复制的说明: RestartStrategy

True if the restart strategy can be applied to restart the ExecutionGraph.

指定者:

canRestart 在接口中 RestartStrategy

返回:

true if restart is possible, otherwise false

restart

public void restart(RestartCallback restarter,
                    ScheduledExecutor executor)

从接口复制的说明: RestartStrategy

Called by the ExecutionGraph to eventually trigger a full recovery. The recovery must be triggered on the given callback object, and may be delayed with the help of the given scheduled executor.

The thread that calls this method is not supposed to block/sleep.

指定者:

restart 在接口中 RestartStrategy

参数:

restarter - The hook to restart the ExecutionGraph

executor - An scheduled executor to delay the restart

toString

public String toString()

覆盖:

toString 在类中 Object

createFactory

public static FailureRateRestartStrategy.FailureRateRestartStrategyFactory createFactory(org.apache.flink.configuration.Configuration configuration)
                                                                                  throws Exception

抛出:
