Description copied from interface: ExecutionDeployer.Factory

Instantiate an ExecutionDeployer with the given params. Note that the version of an execution vertex will be recorded before scheduling executions for it. The version may change if a global failure happens, or if the job is canceled, or if the execution vertex is restarted when all its current execution are FAILED/CANCELED. Once the version is changed, the previously triggered execution deployment will be skipped.

Specified by:

createInstance in interface ExecutionDeployer.Factory

Parameters:

log - the logger

executionSlotAllocator - the allocator to allocate slots

executionOperations - the operations of executions

executionVertexVersioner - the versioner which records the versions of execution vertices.

partitionRegistrationTimeout - timeout of partition registration

allocationReservationFunc - function to reserve allocations for local recovery

mainThreadExecutor - the main thread executor

Returns:

an instantiated ExecutionDeployer
