I just changed a field in a class from a long to a Guid.
The class in question is marked [Serializable] and is passed to Ignite
compute functions as a part of an argument to the compute function and is
not saved to the persistent store.
When I run the modified code against an Ignite grid with a persistent data
store I get the following error. Is this intentional? How should type
evolution ephemeral constructs handed to compute functions in Ignite be
handled?

Etc…..
