Vladimir Ozerov commented on IGNITE-5934:
-----------------------------------------
MVCC support for queries is mostly ready. However, several things need to be
addressed:
1) Perform cleanup in {{MvccQueryTracker}}, so that all TODOs has relevant
tickets.
2) {{GridReduceQueryExecutor.query}} - need to make sure that queries without
caches (e.g. {{SELECT 1}}) works correctly. This also can be done in separate
ticket.
