Pavel Voronkin commented on IGNITE-9113:
----------------------------------------
[~NIzhikov] i also observe that persistent(true) is ignored and region always
created non-persistent. Seems like a bug we shouuld either fail on start or
support persistent regions.
> Allocate memory for a data region when first cache assigned to this region is
> created

> Key: IGNITE-9113
> URL: https://issues.apache.org/jira/browse/IGNITE-9113
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.6
> Reporter: Valentin Kulichenko
> Assignee: Nikolay Izhikov
> Priority: Major
> Fix For: 2.8
>
>
> Currently we do not create any regions or allocate any offheap memory on
> client nodes unless it's explicitly configured. This is good behavior,
> however there is a usability issue caused by the fact that many users have
> the same config file for both server and clients. This can lead to unexpected
> excessive memory usage on client side and forces users to maintain two config
> files in most cases.
> Same issue is applied to server nodes that do not store any data (e.g. nodes
> running only services).
> It's better to allocate memory dynamically, when first cache assigned to a
> data region is created.
> More detailed discussion here:
