> MultiDC support enables stretching single Ignite cluster between 2+ data centers which in turn allows increase data availability by having a copy of data in each DC.
> But spreading copies between DCs requires additional configuration on cache level, and a user could forget or miss this part of configuration.
> To prevent this we need to implement new metrics:
> * A boolean cache metric indicating that configuration may be wrong.
> * A boolean cache metric indicating that with current configuration actual partition distribution between data centers does not have the property "one copy of data in each DC".
