> Current capacity planning guide [1] is too high level and should be elaborated considering
durable memory's internals:
> - memory pages overhead.
> - per-entry overhead (http://apache-ignite-users.70518.x6.nabble.com/Re-Memory-Overhead-per-entry-in-Apache-Ignite-td9498.html).
> - space occupied for indexing needs.
> - free lists
> - etc.
> The page has to include estimates for the Ignite Native Persistence:
> - entry size and its overheads.
> - index size and overheads.
> - data files overheads.
> - estimated WAL size and how to shrink it basing on checkpointing settings.
