ASF GitHub Bot updated ZOOKEEPER-3127: -------------------------------------- Labels: pull-request-available (was: ) > Fixing potential data inconsistency due to update last processed zxid with > partial multi-op txn > ----------------------------------------------------------------------------------------------- > > Key: ZOOKEEPER-3127 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3127 > Project: ZooKeeper > Issue Type: Bug > Components: server > Affects Versions: 3.5.4, 3.6.0, 3.4.13 > Reporter: Fangmin Lv > Priority: Critical > Labels: pull-request-available > Fix For: 3.6.0, 3.5.5, 3.4.14 > > > Found this issue while checking the code for another issue, this is a > relatively rare case which we haven't seen it on prod so far. > Currently, the lastProcessedZxid is updated when applying the first txn of > multi-op, if there is a snapshot in progress, it's possible that the zxid > associated with the snapshot only include partial of the multi op. > When loading snapshot, it will only load the txns after the zxid associated > with snapshot file, which could data inconsistency due to missing sub txns. > To avoid this, we only update the lastProcessedZxid when the whole multi-op > txn is applied to DataTree. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
