Description copied from interface: 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.

Specified by:

createRecoveredCompletedCheckpointStore in interface CheckpointRecoveryFactory

Parameters:

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 claim mode with which the job is restoring.

Returns:

CompletedCheckpointStore instance for the job

Throws:

Exception

createCheckpointIDCounter

public CheckpointIDCounter createCheckpointIDCounter(JobID ignored)

Description copied from interface: CheckpointRecoveryFactory
