> MemoryPolicy configuration and documentation improvements
> ---------------------------------------------------------
>                 Key: IGNITE-5717
>                 URL: https://issues.apache.org/jira/browse/IGNITE-5717
>             Project: Ignite
>          Issue Type: Bug
>    Affects Versions: 2.0
>            Reporter: Sergey Chugunov
>            Priority: Critical
> After introducing MemoryPolicy concept and related settings to Ignite there were several
cases when users run into problems with default configuration.
> It seems that approach with allocating 80% of available physical memory causes confusion
among users sitting on 32bit systems including versions of JMV (example [1]) and also hurts
stability of TeamCity.
> We need to rethink these settings and make them easier to use.
> Also it turned out that memory allocation process differs in cases of PDS on and off;
it must be properly documented.
