                                                                 int maxNumberOfCheckpointsToRetain,

                                                                 Executor ioExecutor,

                                                          throws Exception

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.

参数:

jobId - Job ID to recover checkpoints for

maxNumberOfCheckpointsToRetain - Maximum number of checkpoints to retain

sharedStateRegistryFactory - Simple factory to produce SharedStateRegistry objects.

ioExecutor - Executor used to run (async) deletes.

restoreMode - the restore mode with which the job is restoring.

返回:

CompletedCheckpointStore instance for the job

抛出:

Exception

createCheckpointIDCounter

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

Creates a CheckpointIDCounter instance for a job.

参数:

jobId - Job ID to recover checkpoints for

返回:

CheckpointIDCounter instance for the job

抛出:
