[infinispan-issues] [JBoss JIRA] (IPROTO-119) Introduce a customizable TypeId mapper to support changing type ids (and names) for schema evolution

[Nistor Adrian (Jira)]

    [ https://issues.jboss.org/browse/IPROTO-119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13791385#comment-13791385 ] 

Nistor Adrian commented on IPROTO-119:
--------------------------------------

This is fixed now, but I have second thoughts about it. Since we do not maintain any state in the WrappedMessageTypeMapper callback we cannot know if we are invoked by an old client that needs TypeId translation or not. Also, we need to introduce an option to discard the TypeId. A possible solution would be to return a negative value from WrappedMessageTypeMapper.mapTypeId.  I also have second thought about WrappedMessageTypeMapper.mapTypeName. Type names should never change during schema evolution. We could allow that for more flexibility, but I'd rather remove that and keep things as simple as possible.
