Ssserj, as for the persistence issue you are talking about - you are
hitting the issue [1] which is almost finished, but did not make it to the
2.4 release. As the affects version is 2.1, this is not a regression, so I
do not think this issue is a blocker for the release.

Re: Data eviction/expiration from Ignite persistence

[Alexey Goncharuk]

The ticket [1] is in patch available state looks good, the only thing left
there is to transfer old entries to new storage. I hope Andrey will have
time to finish this soon, so we can target the fix for 2.5.
