>                 Key: IGNITE-8483
>                 URL: https://issues.apache.org/jira/browse/IGNITE-8483
>             Project: Ignite
>          Issue Type: Improvement
>          Components: cache
>            Reporter: Andrew Mashenkov
>            Priority: Minor

> For in memory cache pending tree root page is allocated when ignite store is initializing
even if no ExpiryPolicy is used. 
>  We have to implement lazy PendingTree initialization and switch to per-partition based
PendingTree as we've done for persistent caches.
> Switching to per-partition based PendingTree without lazy initialization will bump us
with 1024 (default partitioned cache settings) unevictable pages per CacheGroup if no ExpiryPolicy
is used.
