> Key: IGNITE-6182
> URL: https://issues.apache.org/jira/browse/IGNITE-6182
> Project: Ignite
> Issue Type: Task
> Components: general
> Affects Versions: 2.1
> Reporter: Vladimir Ozerov
> Assignee: Igor Seliverstov
> Priority: Blocker
> Fix For: 2.2
>
>
> Currently we can allocate up to 80% of available RAM by default. It could
> lead to swap with potential risk of hang.
> In order to improve user experience, we need to do the following:
> 1) Decrease default to 20%
> ({{MemoryConfiguration.DFLT_MEMORY_POLICY_FRACTION}})
> 2) When node starts it should sum max sizes of all memory regions plus Java's
> XMX. If result is greater than 50% of total RAM, we should issue a warning
> about potential swap.
