从接口复制的说明: CheckpointRecoveryFactory

Creates a RECOVERED CompletedCheckpointStore instance for a job. In this context, RECOVERED means, that if we already have completed checkpoints from previous runs, we should use them as the initial state.

指定者:

createRecoveredCompletedCheckpointStore 在接口中 CheckpointRecoveryFactory

参数:

jobId - Job ID to recover checkpoints for

maxNumberOfCheckpointsToRetain - Maximum number of checkpoints to retain

userClassLoader - User code class loader of the job

返回:

CompletedCheckpointStore instance for the job

createCheckpointIDCounter

public CheckpointIDCounter createCheckpointIDCounter(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: CheckpointRecoveryFactory

Creates a CheckpointIDCounter instance for a job.

指定者:

createCheckpointIDCounter 在接口中 CheckpointRecoveryFactory

参数:

jobId - Job ID to recover checkpoints for

返回:

CheckpointIDCounter instance for the job
