Review Comment:
Possible memory leak here. E.g:
```java
// deserialized message id {batchSize = 2, batchIndex = 1}
// and { batchIndex = 0 } already has been acked before.
MessageId msgId = MessageId.fromByteArray(msgId.toByteArray());
consumer.acknowledge(msgId);
// then the acker in the map will no longer be released.
```
