Class RestartStrategies

java.lang.Object

org.apache.flink.api.common.restartstrategy.RestartStrategies

@PublicEvolving
public class RestartStrategies
extends Object

This class defines methods to generate RestartStrategyConfigurations. These configurations are used to create RestartStrategies at runtime.

The RestartStrategyConfigurations are used to decouple the core module from the runtime module.

Method Detail

noRestart

public static RestartStrategies.RestartStrategyConfiguration noRestart()

Generates NoRestartStrategyConfiguration.

Returns:

NoRestartStrategyConfiguration

fallBackRestart

public static RestartStrategies.RestartStrategyConfiguration fallBackRestart()

fixedDelayRestart

public static RestartStrategies.RestartStrategyConfiguration fixedDelayRestart(int restartAttempts,
                                                                               long delayBetweenAttempts)

Generates a FixedDelayRestartStrategyConfiguration.

Parameters:

restartAttempts - Number of restart attempts for the FixedDelayRestartStrategy

Returns:

FixedDelayRestartStrategy

fixedDelayRestart

public static RestartStrategies.RestartStrategyConfiguration fixedDelayRestart(int restartAttempts,
                                                                               Time delayInterval)

Generates a FixedDelayRestartStrategyConfiguration.

Parameters:

restartAttempts - Number of restart attempts for the FixedDelayRestartStrategy

delayInterval - Delay in-between restart attempts for the FixedDelayRestartStrategy

Returns:

FixedDelayRestartStrategy

failureRateRestart

public static RestartStrategies.FailureRateRestartStrategyConfiguration failureRateRestart(int failureRate,
                                                                                           Time failureInterval,
