> Key: IGNITE-18433
> URL: https://issues.apache.org/jira/browse/IGNITE-18433
> Project: Ignite
> Issue Type: Task
> Reporter: Kirill Tkalenko
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> Scenarios for testing: (current storages: *TxStateStorage* and
> *MvPartitionStorage*)
> * During a full rebalance, the leader changes, what will happen?
> I expect the current rebalance to be canceled and a new one to start with
> empty storages and set initial (equal to 0) *lastAppliedIndex *and
> *lastAppliedTerm*.
> And also what index will be sent to the new leader, if during a full
> rebalancing on the recipient it will be equal to *-1*.
> * What happens if a leader changes during a full rebalance that has enough
> log to avoid a full rebalance?
> I expect the full rebalance to be canceled, clear the storages and set the
> initial (equal to 0) *lastAppliedIndex *and *lastAppliedTerm*.
> And also what index will be sent to the new leader, if during a full
> rebalancing on the recipient it will be equal to *-1*.
> * Suppose a full rebalancing for one of the storages ended successfully, and
> it has updated (not equal to -1) *lastAppliedIndex *and *lastAppliedTerm*,
> while for the other we did not have time to complete the full rebalancing and
> the node fell.
> What will happen to both storages after the node is powered on?
> I expect both stores to be cleared and have initial (equal to 0)
> *lastAppliedIndex *and *lastAppliedTerm*.
> Each scenario can be tested in a separate ticket
