Vladislav Pyatkov commented on IGNITE-8873:
-------------------------------------------
I think, that will to by done across preload every partition pages before
iterate over entry.
And other idea: to implement specific configuration parameter (like
\{{CacheConfiguration#warnUpOnStart(boolean)}}), that preload all pages from
storage for particular cache (cache group) after the cache started.
Anyone have idea, how to implement it in public API?
