---------------------------------------

             Summary: Document MVCC continuous queries
                 Key: IGNITE-9888
                 URL: https://issues.apache.org/jira/browse/IGNITE-9888
             Project: Ignite
          Issue Type: Task
          Components: documentation
            Reporter: Vladimir Ozerov
            Assignee: Artem Budnikov
             Fix For: 2.7


Key differences with continuous queries for non-MVCC caches:
1) When event is received, subsequent read of the same key may still return previous value for some time (i.e. no guarantee of happens-before between event and subsequent read)
2) Keys for notification are kept in memory. If transaction is too large, OOME could happen. In order to avoid that, we skip notification of too large transactions.

[~rkondakov], could you please elaborate on how is this implemented?
