Summary: MVCC TX: Send partition update counters to backup nodes on prepare state. Key: IGNITE-9538 URL: https://issues.apache.org/jira/browse/IGNITE-9538 Project: Ignite Issue Type: Task Components: cache, mvcc Reporter: Igor Seliverstov Assignee: Igor Seliverstov Fix For: 2.7 There are several issues with partition update counters consistency in transactional caches. The next approach solves most of them: # Count per-partition updates # on prepare state on primary node update current partition counter incrementing it by per-partition updates count and send initial value with updates count to backup nodes # on backup nodes hold all pending updates and update partition update counter applying the lowest gapless update (on tx finish). # on historical rebalance use partition update counter as start point. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
