类 AcceptorExecutor<ID,T>

java.lang.Object

com.alipay.sofa.registry.task.batcher.AcceptorExecutor<ID,T>

public class AcceptorExecutor<ID,T>
extends Object

An active object with an internal thread accepting tasks from clients, and dispatching them to workers in a pull based manner. Workers explicitly request an item or a batch of items whenever they are available. This guarantees that data to be processed are always up to date, and no stale data processing is done.

Task identification

Each task passed for processing has a corresponding task id. This id is used to remove duplicates (replace older copies with newer ones).

Re-processing

If data processing by a worker failed, and the failure is transient in nature, the worker will put back the task(s) back to the AcceptorExecutor. This data will be merged with current workload, possibly discarded if a newer version has been already received.
