Interesting things about those LINQPad/JPad scenarios. Was not aware
of it. Still some doubts about applicability. It seems to me that JPad
having work dir in "Program Files" have a lot of problems by itself,
e.g. a user is not able to run basic file IO snippets with relative
file paths.

Am I getting it right that in your PR if we have a limit N than
returned items (at most N) will not be strictly the most relevant
ones? E.g. if one node returned N items faster than others but with
not so good relevance?

Yes, your observation is correct.
This behavior lasts from the very beginning when Lucene indexing was
implemented for distributed queries.
Implementation of the *limit* solves the problem of redundant response
size. Without it *ALL* off the records are fetched each time; that is not
good,

Thank you, fine with it.

I checked the IEP [1]. Now it is more clear for me about SystemView

That's a very useful metric which we already discussed in the past. This

Actually, I don't agree with you.
Having external monitoring system for any production cluster is a *basic* thing.

As I understand, RunningQueryManager track query only for an export.
So we don't need explicit entity for that, we already have System Views.

Nikolay,
Many users start to use Ignite with a small project without
production-level monitoring. When proof-of-concept appears to be viable,
they tend to expand Ignite usage by growing cluster and adding needed

I agree that we should have the ability to read any metric using simple

remember correctly, it will start a daemon node which will bump the

it will beneficial to
Maxim,
Having a cluster-wide lock for a cache does not improve availability of the
solution. A user cannot defragment a cache if the cache is involved in a
mission-critical operation, so having a lock on such a cache is equivalent
to the whole cluster shutdown.
We should decide between either a s

Not quite. Also it is responsible for explicit query cancellation and
running queries cancellation on node stop. I do not think that a view
should be responsible for it.

I'm for the proposal to add new JMX metrics and enhance the existing

framework Nikolay has been working on. Otherwise, we will be deprecating
