Ignite seems amazing cool; hoping to start using it to replace some middleware components that we are still using and still trying to learn everything.
Read a lot of docs and books, but still had a hopefully simple question ; what happens if there is already a cache defined in the cluster and then either in config of a new node, or in Java code it attempts to get created again but with a different configuration?
Configuration of existing cache (with the same name) will be used and new configuration of joining node will be discarded (provided you do that with getOrCreateCache()).
Most of cache settings cannot be changed once cache is created.
