>             Project: Ignite
>          Issue Type: Improvement

> Currently MVCC caches are not allowed to be located in data regions with enabled page
evictions in in-memory mode because unexpected data purges may lead to repeatable read semantics
violations. See this [thread|http://apache-ignite-developers.2346864.n4.nabble.com/Page-eviction-for-in-memory-mode-with-enabled-MVCC-tt39460.html]
on dev-list for details.
> We need to think about a suitable solution to this problem and implement it.
> See branch professional/ignite-10448-proto for prototype.
