[jira] [Updated] (IGNITE-24056) Prompt stop of Raft state machines

["Roman Puchkovskiy (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-24056?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Roman Puchkovskiy updated IGNITE-24056:
---------------------------------------
    Description: 
If a Raft state machine (represented with a RaftGroupListener) starts executing a batch of commands which is huge, there is no way to stop it midway (apart from closing a storage it interacts with). This, among other things, does not allow us to stop an Ignite node timely if some Raft node recovers from a huge Raft log.

Here is how we can do it:
 # As soon as Raft node's shutdown is initiated, make the currently executed iterator return false from hasNext()
 # When such an iterator 'finishes', complete all command closures that were not handled due to an early stop with a ShutdownException
