Creates RestartBackoffTimeStrategy.Factory from the given configuration.

The strategy factory is decided in order as follows:

1. Strategy set within job graph, i.e. RestartStrategies.RestartStrategyConfiguration, unless the config is RestartStrategies.FallbackRestartStrategyConfiguration.
2. Strategy set in the cluster(server-side) config (flink-conf.yaml), unless the strategy is not specified
3. FixedDelayRestartBackoffTimeStrategy.FixedDelayRestartBackoffTimeStrategyFactory if checkpointing is enabled. Otherwise NoRestartBackoffTimeStrategy.NoRestartBackoffTimeStrategyFactory

Parameters:

jobRestartStrategyConfiguration - restart configuration given within the job graph

clusterConfiguration - cluster(server-side) configuration

isCheckpointingEnabled - if checkpointing is enabled for the job

Returns:

new version restart strategy factory
