Subject [jira] [Created] (IGNITE-5717) MemoryPolicy configuration and documentation improvements
Date Fri, 07 Jul 2017 10:52:00 GMT
Sergey Chugunov created IGNITE-5717:

             Summary: MemoryPolicy configuration and documentation improvements
                 Key: IGNITE-5717
                 URL: https://issues.apache.org/jira/browse/IGNITE-5717
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergey Chugunov

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.
