Andrew Mashenkov updated IGNITE-8483:
-------------------------------------
Description:
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.
