Hello Steve, I've looked at Persistent Collectors library, but don't see any big advantages to use it inside Ignite right now. Why do you think, that marshalling/unmarshalling process will be speeded up with this library? As I can see there are no explicit changes in serialization process, just added persistent ability to regular java collections.
