CacheMetrics update and rolling upgrades.

Pavel Pereslegin
Hi, Igniters!

I’m working on IGNITE-6333 [1] and I need to add two new metrics into
CacheMetrics.
As I see, versioning is not supported for now.
Do I need to care about rolling upgrades?

Hello Pavel,

Could you share the signature of the new metrics with us hear? The community will be happy to provide a feedback.

What do you mean under the rolling upgrade? There is no such a feature in Ignite.

Thank you, Denis.

I added two additional fields for serialization into CacheMetrics and
I was worried about compatibility with old version (for example, when
partial cluster upgrade is in progress). But since Ignite does not
provide such feature as rolling upgrades, I think this question can be
considered solved.
