Method Summary

Modifier and Type	Method	Description
ExecutionDeployer	createInstance(org.slf4j.Logger log, ExecutionSlotAllocator executionSlotAllocator, ExecutionOperations executionOperations, ExecutionVertexVersioner executionVertexVersioner, Duration partitionRegistrationTimeout, BiConsumer<ExecutionVertexID,AllocationID> allocationReservationFunc, org.apache.flink.runtime.concurrent.ComponentMainThreadExecutor mainThreadExecutor)	Instantiate an ExecutionDeployer with the given params.

Method Details

createInstance

ExecutionDeployer createInstance(org.slf4j.Logger log,
 ExecutionSlotAllocator executionSlotAllocator,
 ExecutionOperations executionOperations,
 ExecutionVertexVersioner executionVertexVersioner,
 Duration partitionRegistrationTimeout,
 BiConsumer<ExecutionVertexID,AllocationID> allocationReservationFunc,
 org.apache.flink.runtime.concurrent.ComponentMainThreadExecutor mainThreadExecutor)

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.

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
