> 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.
