[hazelcast-3] add custom serializer at runtime

[lb]

Hi,
I would like to know if the new Hazelcast 3 serialization engine can be enriched at run-time - after an instance has already been created, something like:
 

myHazelcastInstance.getConfig().getSerializationConfig().addTypeSerializer(
    new TypeSerializerConfig().
    setTypeClass(MyType.class).
    setImplementation(new CustomerSerializer()));

Cheers,
Luca

I'm currently working on some projects based on OSGi and what I was thinking about is to dynamically register serializers when bundles are installed.

My OSGi based application/framework uses Hazelcast as caching and communication framework and I would like to decouple the core services from the features ones not only in term of class dependencies but also in term of availability as in OSGi services can be added/removed at run-time.

So I imagine something like:

- a core Hazelcast service that:
  - creates the Hazelcast instance and register it as OSGi service
  - listen for service registration/de-registration and if a service is of type ISerializer (e.g.) , add a new type serializer to Hazelcast
- some features (bundles) that implement and export an ISerializer service if a custom serialization is required

Sounds reasonable?
