--------------------------------------
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.
