Denis Chudov updated IGNITE-28416:
----------------------------------
Description:
This requires adding communication / synchronization between txn coordinator
and enlisted partitions. The placement driver would know how to move the txn
data from the original primary to the new one. Some txns may still have to
rollback, e.g. if the new primary has already locked data that was locked on
the old primary for this txn.
This feature would bring even more resiliency than IGNITE-28415 , but
incremental benefit is less and complexity is more than that ticket.
