Subject Re: Page Memory behavior with default memory policy
Date Wed, 19 Apr 2017 09:34:03 GMT
Guys,

I created a ticket to implement these improvements, please take a look:
IGNITE-5024 <https://issues.apache.org/jira/browse/IGNITE-5024>

Besides employing the idea of allocation 80% of physical memory I'm also
suggesting to introduce one more configuration property to specify default
MemoryPolicy's size in bytes without having to use verbose syntax of
*memoryPolicyConfiguration
*section.

Any thoughts on this?

Thanks,
Sergey.
