方法详细资料

getConnectionId

public ConnectionID getConnectionId()

getResultPartitionID

public ResultPartitionID getResultPartitionID()

指定者:

getResultPartitionID 在接口中 ShuffleDescriptor

storesLocalResourcesOn

public Optional<ResourceID> storesLocalResourcesOn()

从接口复制的说明: ShuffleDescriptor

Returns the location of the producing task executor if the partition occupies local resources there.

Indicates that this partition occupies local resources in the producing task executor. Such partition requires that the task executor is running and being connected to be able to consume the produced data. This is mostly relevant for the batch jobs and blocking result partitions which can outlive the producer lifetime and be released externally. ShuffleEnvironment.releasePartitionsLocally(Collection) can be used to release such kind of partitions locally.

指定者:

storesLocalResourcesOn 在接口中 ShuffleDescriptor

返回:

the resource id of the producing task executor if the partition occupies local resources there

isLocalTo

public boolean isLocalTo(ResourceID consumerLocation)
