             Summary: MVCC: Document TX updates visibility changes for 
continuous queries.
                 Key: IGNITE-9763
                 URL: https://issues.apache.org/jira/browse/IGNITE-9763
             Project: Ignite
          Issue Type: Task
          Components: mvcc
            Reporter: Roman Kondakov
             Fix For: 2.7


We should document visibility behaviour changes for MVCC transactions in 
Continuous Queries context: when MVCC transaction completes, it's updates are 
not visible immediately for the new transaction even they are started in 
continuous query listener. This is caused by the lag between transaction 
completes on the node and mvcc coordinator removes this transaction from the 
active list. Therefore all transactions started during this little time gap 
between these events will see just completed transaction as active in their 
snapshot, and, consequently, can't observe it's updates.
