Deploy different class versions to ignite cluster

[Surinder Mehra <re...@gmail.com>]

Hi,
I have a special requirement to support deploying several versions of same
class file on same ignite cluster. Say customer 1 wants some additional
features on same file but other clients continue working with old version.
Just trying to think if it is possible in ignite or i have to think about
having separate ignite cluster for each version.

“Classes deployed within the same class loader on the master node still share the same class loader remotely on worker nodes. However, the tasks deployed from different master nodes does not share the same class loader on worker nodes. This is useful in development environments when different developers can be working on different versions of the same classes"

Does this mean same ignite node can use dufferent app libs to execute
business logic. Or does a node takes lib version at startup and only
process that version through its life cycle, and it is part of same cluster
cobtaining other nodes with different app version. Could you please point
me to documentation if any.

You might need to set the deployment mode to PRIVATE/ISOLATED but otherwise it should pretty much just work.
