类 AsyncSinkBase<InputT,RequestEntryT extends Serializable>

java.lang.Object

org.apache.flink.connector.base.sink.AsyncSinkBase<InputT,RequestEntryT>

所有已实现的接口:

Serializable, org.apache.flink.api.connector.sink2.Sink<InputT>, org.apache.flink.api.connector.sink2.StatefulSink<InputT,BufferedRequestState<RequestEntryT>>

@PublicEvolving
public abstract class AsyncSinkBase<InputT,RequestEntryT extends Serializable>
extends Object
implements org.apache.flink.api.connector.sink2.StatefulSink<InputT,BufferedRequestState<RequestEntryT>>

A generic sink for destinations that provide an async client to persist data.

The design of the sink focuses on extensibility and a broad support of destinations. The core of the sink is kept generic and free of any connector specific dependencies. The sink is designed to participate in checkpointing to provide at-least once semantics, but it is limited to destinations that provide a client that supports async requests.

Limitations:

• The sink is designed for destinations that provide an async client. Destinations that cannot ingest events in an async fashion cannot be supported by the sink.
• The sink usually persist InputTs in the order they are added to the sink, but reorderings may occur, eg, when RequestEntryTs need to be retried.
• We are not considering support for exactly-once semantics at this point.
