Hi Sergey,

If Ignite persistence is enabled, then the page-based evictions have no effect 
because the oldest pages will be purged from memory automatically.

Updated the text of the warning to makes things clearer.

> configurations?

Yes, you can have the persistence enabled for region A and disabled for region 
B.

Page eviction mode is ignored

[Sergey Sergeev]

Hi,

I'm confused. After the successful launch of the Ignite cluster version
2.3.0, I saw the WARN message:
WARN  GridCacheDatabaseSharedManager - Page eviction mode for [inMemory]
memory region is ignored because Ignite Native Persistence is enabled

Ignite spring config see below:

...


































...



But... page eviction doesn't work for "inMemory" memory region... Why?
Does Ignite supports a mix (persistenceEnabled or not) of DataRegion
configurations?
