@FunctionalInterface
public interface LocallyCleanableResource

LocallyCleanableResource is supposed to be implemented by any class that provides artifacts for a given job that need to be cleaned up after the job reached a local terminal state. Local cleanups that needs to be triggered for a global terminal state as well, need to be implemented using the GloballyCleanableResource.

The DispatcherResourceCleanerFactory provides a workaround to trigger some LocallyCleanableResources as globally cleanable. FLINK-26175 is created to cover a refactoring and straighten things out.

方法详细资料

localCleanupAsync

CompletableFuture<Void> localCleanupAsync(org.apache.flink.api.common.JobID jobId,
                                          Executor cleanupExecutor)

localCleanupAsync is expected to be called from the main thread. Heavy IO tasks should be outsourced into the passed cleanupExecutor. Thread-safety must be ensured.

参数:

jobId - The JobID of the job for which the local data should be cleaned up.

cleanupExecutor - The fallback executor for IO-heavy operations.

返回:

The cleanup result future.
