Subject Re: Apache Ignite 2.5 release
Date Thu, 17 May 2018 15:53:28 GMT
Denis,

The issue with page corruption may manifest itself when a node is stopped
during partition eviction (basically, a random chance on topology change
scenario).

The issue with WAL iterator can manifest during historical rebalancing
(this is less likely than the previous issue).
