   ### Search before asking
   
   - [X] I searched in the 
[issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing 
similar.
   
   
   ### Version
   
   master
   
   ### Minimal reproduce step
   
   Reproducible code:
   ```cpp
   TEST_P(MessageChunkingTest, testEndToEnd) {
       const std::string topic =
           "MessageChunkingTest-EndToEnd-" + toString(GetParam()) + 
std::to_string(time(nullptr));
       Consumer consumer;
       createConsumer(topic, consumer);
       Producer producer;
       createProducer(topic, producer);
   
       constexpr int numMessages = 10;
   
       std::vector<MessageId> sendMessageIds;
       for (int i = 0; i < numMessages; i++) {
           MessageId messageId;
           ASSERT_EQ(ResultOk, 
producer.send(MessageBuilder().setContent(largeMessage).build(), messageId));
           auto chunkMsgId =
               
std::dynamic_pointer_cast<ChunkMessageIdImpl>(PulsarFriend::getMessageIdImpl(messageId));
           ASSERT_TRUE(chunkMsgId);
           LOG_INFO("Send " << i << " to " << messageId);
           sendMessageIds.emplace_back(messageId);
       }
   
       Message msg;
       std::vector<MessageId> receivedMessageIds;
       for (int i = 0; i < numMessages; i++) {
           ASSERT_EQ(ResultOk, consumer.receive(msg, 3000));
           LOG_INFO("Receive " << msg.getLength() << " bytes from " << 
msg.getMessageId());
           ASSERT_EQ(msg.getDataAsString(), largeMessage);
           ASSERT_EQ(msg.getMessageId().batchIndex(), -1);
           ASSERT_EQ(msg.getMessageId().batchSize(), 0);
           auto messageId = msg.getMessageId();
           auto chunkMsgId =
               
std::dynamic_pointer_cast<ChunkMessageIdImpl>(PulsarFriend::getMessageIdImpl(messageId));
           ASSERT_TRUE(chunkMsgId);
           receivedMessageIds.emplace_back(messageId);
           consumer.acknowledge(messageId);
       }
       ASSERT_EQ(receivedMessageIds, sendMessageIds);
       ASSERT_EQ(receivedMessageIds.front().ledgerId(), 
receivedMessageIds.front().ledgerId());
       ASSERT_GT(receivedMessageIds.back().entryId(), numMessages);
   
       // Verify the cache has been cleared
       auto& chunkedMessageCache = 
PulsarFriend::getChunkedMessageCache(consumer);
       ASSERT_EQ(chunkedMessageCache.size(), 0);
   
       BrokerConsumerStats consumerStats;
       waitUntil(
           std::chrono::seconds(10),
           [&] {
               if (consumer.getBrokerConsumerStats(consumerStats) != ResultOk) 
return false;
               LOG_DEBUG(consumerStats);
               return consumerStats.getMsgBacklog() == 0;
           },
           1000);
       ASSERT_EQ(consumerStats.getMsgBacklog(), 0); // Msg back log doesn't get 
cleared
   
       producer.close();
       consumer.close();
   }
   ```
   
   ### What did you expect to see?
   
   The message backlog should be cleared. The above test should be passed.
   
   ### What did you see instead?
   
   The backlog doesn't get cleared.
   
   ### Anything else?
   
   The root cause is the consumer doesn't acknowledge all chunk message Ids
   
   ### Are you willing to submit a PR?
   
   - [X] I'm willing to submit a PR!
