Valentin Kulichenko commented on IGNITE-6846:
---------------------------------------------

How do we calculate times for other operations, on server or on client? If the 
latter, then I think we can just remove `ReadOnly` times. If on server, you 
should be able to easily calculate this though.

9. This is a very weird case, so I don't think it really matters. But since 
this EP removes entry at the end, let's count it as removal.

10. In my view, it's a missed read and then removal. What exactly is 
non-trivial here?

> {{CacheMetrics}} object has multiple metrics for various cache operations 
> like {{get}}, {{put}} and {{remove}}, but nothing for 
> {{invoke}}/{{EntryProcessor}}. It makes sense to add such metrics, for 
> example:
> * Total number of `invoke` operations executed.
> * Number of `invoke` operations that included updates.
> * Number of read-only `invoke` operations.
> * Min/max/avg execution time.
