Package org.apache.pulsar.client.impl

Class CompactionReaderImpl<T>

java.lang.Object

org.apache.pulsar.client.impl.ReaderImpl<T>

org.apache.pulsar.client.impl.CompactionReaderImpl<T>

All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.pulsar.client.api.Reader<T>

public class CompactionReaderImpl<T>
extends ReaderImpl<T>

An extended ReaderImpl used for StrategicTwoPhaseCompactor. The compaction consumer subscription is durable and consumes compacted messages from the earliest position. It does not acknowledge the message after each read. (needs to call acknowledgeCumulativeAsync to ack messages.)
