-----------------------------------
Fix Version/s: (was: 3.0)
> [Native Persistence 3.0] Checkpoint, lifecycle and file store refactoring and
> re-implementation
> -----------------------------------------------------------------------------------------------
>
> Key: IGNITE-15818
> URL: https://issues.apache.org/jira/browse/IGNITE-15818
> Project: Ignite
> Issue Type: Task
> Reporter: Sergey Chugunov
> Priority: Major
> Labels: ignite-3
>
> 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
