Roman Kondakov reassigned IGNITE-8371: -------------------------------------- Assignee: Roman Kondakov (was: Sergey Kalashnikov) > MVCC TX: Force key request during rebalance may cause error on backups. > ----------------------------------------------------------------------- > > Key: IGNITE-8371 > URL: https://issues.apache.org/jira/browse/IGNITE-8371 > Project: Ignite > Issue Type: Bug > Components: sql > Reporter: Roman Kondakov > Assignee: Roman Kondakov > Priority: Major > Labels: mvcc > > When backup is updating during rebalance and the key to be updated in TX is > not supplied yet from the previous partition owner, backup makes force key > request in order to obtain this key and all its versions. But later this key > can be send to this backup from the previous owner once again as a part of > standard rebalance process. And this causes write conflict: we have to write > this key on the backup once again. > Solution: do not update key when it has already been written before (during > rebalance or force key request process). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
