类 BKStateStoreImpl

java.lang.Object

org.apache.pulsar.functions.instance.state.BKStateStoreImpl

所有已实现的接口:

AutoCloseable, org.apache.pulsar.functions.api.state.ByteBufferStateStore, org.apache.pulsar.functions.api.state.CounterStateStore, org.apache.pulsar.functions.api.StateStore, DefaultStateStore

public class BKStateStoreImpl
extends Object
implements DefaultStateStore

This class accumulates the state updates from one function.

currently it exposes incr operations. but we can expose other key/values operations if needed.
