Create and restore ExecutionGraph from the given JobGraph and services.

Parameters:

jobGraph - jobGraph to initialize the ExecutionGraph with

completedCheckpointStore - completedCheckpointStore to pass to the CheckpointCoordinator

checkpointsCleaner - checkpointsCleaner to pass to the CheckpointCoordinator

checkpointIdCounter - checkpointIdCounter to pass to the CheckpointCoordinator

checkpointStatsTracker - The CheckpointStatsTracker that's used for collecting the checkpoint-related statistics.

partitionLocationConstraint - partitionLocationConstraint for this job

initializationTimestamp - initializationTimestamp when the ExecutionGraph was created

vertexAttemptNumberStore - vertexAttemptNumberStore keeping information about the vertex attempts of previous runs

vertexParallelismStore - vertexMaxParallelismStore keeping information about the vertex max parallelism settings

executionStateUpdateListener - listener for state transitions of the individual executions

log - log to use for logging

executionPlanSchedulingContext - execution plan scheduling context that retrieve execution context details for adaptive batch jobs

Returns:

restored ExecutionGraph

Throws:

Exception - if the ExecutionGraph could not be created and restored
