Hi,

I understand and experience that Ignite crashes (binaryobjectexceeptions)
when I redeploy my application (with an embedded Ignite server node) in a
cluster and the new redeployed application has a different model (like enums
with added values).

This results in the inability to have my application up 24/7 because I can't
do rolling updates. It suggest I need to kill all my application instances
(and thus the embedded Ignite instances) first and then deploy and restart
them. But this is not acceptable.

How do I need to configure Ignite to be able to do rolling updates with
changing models? If this is not possible, what is the use of Ignite as a
distributed cache?

Configuration details:
- server nodes only
- non persistent
- cached replicated (in fact I am only interested in distributed cache
invalidations)
- server nodes run embedded in/from a java/spring/tomcat application

Kind regards,

Roger Janssen
