jiazhai opened a new issue #4940: Serialization and Deserialization for MultiMessageIdImpl
URL: https://github.com/apache/pulsar/issues/4940
 
 
   In PR #4911, we added MultiMessageIdImpl, which contains a Map of <topic, MessageId>, that could be used for partition/multi-topics/pattern consumer methods, e.g. seek(), ackCumulative(), getLastMessageId().
   
   In streaming applications, they tends to store messageId along with the state. so that the streaming applications can restore the state back. we need to provide a consistent behavior for how to serialize and deserialize different message id implementations.
   
   This issue is to track and discuss uniforming the serialization and deserialization of message id implementations (basically we need the ability to deserialize the message ids from the byte array in a consistent way).
