Kirill Tkalenko updated IGNITE-17230:
-------------------------------------
Description:
*Notes*
Description may not be complete.
*Goal*
To implement the new checkpoint (described in IGNITE-15818), we need to modify
{*}FilePageStore{*}.
A list (from new to old) of *DelataFilePageStore* will be added to its
structure, which will increase after each checkpoint (at its completion) and
decrease after each merge with the *FilePageStore* by "compacter".
*DelataFilePageStore* will contain:
* Sorted list of {*}pageId{*}: allows by binary search to find the offset in
this file for the requested {*}pageId{*};
* Allocation Index: *pageId* of the last allocated page;
* Pages themselves are sorted by {*}pageId{*}.

structure, which will increase after each checkpoint (at its completion) and
decrease after each merge with the *FilePageStore* by "compacter".
