[infinispan-issues] [JBoss JIRA] (ISPN-2362) Potential inconsistency during NBST

Mircea Markus created ISPN-2362: ----------------------------------- Summary: Potential inconsistency during NBST Key: ISPN-2362 URL: https://issues.jboss.org/browse/ISPN-2362 Project: Infinispan Issue Type: Feature Request Components: State transfer Affects Versions: 5.2.0.Alpha3 Reporter: Mircea Markus Assignee: Dan Berindei Priority: Critical Fix For: 5.2.0.CR1 The NBST functionality leaves place to inconsistencies during removals: 1. the joiner first requests transaction data 2. after all transaction data is integrated (i.e. tx is prepared on the state receiver node) it requests the rest of the data (from data container) 3. in order not to override the data from transactions which is more recent (transactions at step 1 might have been committed during step 2), the data at 2 inserts data in the cache with putIfAbsent. Whilst this prevents from overriding newer values as written by transactions, it doesn't guard against the situation in which the tx removed data. So it is possible for deleted data a to resurrect. A possible solution to this inconsistency issue is by using tombstones for the duration of the state transfer. -- This message is automatically generated by JIRA.
