Alexander Paschenko updated IGNITE-4637:
----------------------------------------
Description:
*Normal flow*
1) When participating node completed operation, it sends
{{PARTICIPANT_FINISHED}} message to coordinator.
2) When coordinator collected responses from all participants, it notifies
originator with {{FINISHED}} request.
3) Originator responds coordinator with {{FINISHED_ACK}} message.
4) Coordinator responds to all peers with {{PARTICIPANT_FINISHED_ACK}} message.
*Originator leave*
1) Coordinator marks originator as "notified", and sends
{{PARTICIPANT_FINISHED_ACK}} message to participants after all
{{PARTICIPANT_FINISHED}} are collected.
*Participant leave*
1) Coordinator marks participant as "finished" and no longer waits for any
responses from it.
*Coordinator leave*
1) The oldest node among remaining participants is elected as new coordinator.
2) Coordinator *polls* explicitly operation state from participants with
{{IS_PARTICIPANT_FINISHED}} message.
3) Participants re-send {{PARTICIPANT_FINISHED}} message to new coordinator.
4) If all participant nodes have left, originator feature is completed with
error.
