[jira] [Created] (IGNITE-6526) Ignite 2.x capacity planning guide

Denis Magda created IGNITE-6526:
-----------------------------------

             Summary: Ignite 2.x capacity planning guide
                 Key: IGNITE-6526
                 URL: https://issues.apache.org/jira/browse/IGNITE-6526
             Project: Ignite
          Issue Type: Task
            Reporter: Denis Magda


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.
