Index rebuilding metrics

Hello, Igniters.

I would like to implement index rebuilding metrics [1, 2].
I suggest adding a cache metric and system view that shows if there
are any index rebuilding for this cache right now (boolean type) [3].

Also, I can add time metrics:
- how long was index rebuilding (or current duration)
- when index rebuilding was ended.
Do we need such time metrics?

Nikolay,

I mean adding a column to the existing indexes system view
(SqlIndexView), not a new view.

Hello, Nikita.

Thanks for picking this up.

Are you talking about new system view?
Why do we need it?

We already have INDEXES system view that show info about each index existing on the Ignite node.
Can we add some columns to it to reflect state of index rebuild process?
