> h2. Goal
> Port and refactor core classes implementing page-based persistent store in Ignite 2.x: GridCacheOffheapManager, GridCacheDatabaseSharedManager, PageMemoryImpl, Checkpointer, FileWriteAheadLogManager.
> New checkpoint implementation to avoid excessive logging.
> Store lifecycle clarification to avoid complicated and invasive code of custom lifecycle managed mostly by DatabaseSharedManager.
> h2. Items to pay attention to
> New checkpoint implementation based on split-file storage, new page index structure to maintain disk-memory page mapping.
> File page store implementation should be extracted from GridCacheOffheapManager to a separate entity, target implementation should support new version of checkpoint (split-file store to enable always-consistent store and to eliminate binary recovery phase).
> Support of big pages (256+ kB).
> Support of throttling algorithms.
> h2. References
> New checkpoint design overview is available [here|https://github.com/apache/ignite-3/blob/ignite-14647/modules/vault/README.md]
