Looks like we didn't rich consensus here.
Igor, as thin client maintainer, can you please share your opinion?
Everyone else also welcome, please share your thoughts about options to
implement operations for compute.

Hi Saikat,
Let's wait while Alex Goncharuk checks a similar PR here:

Hello, Pavel.
> there should be an obvious public API to retrieve metrics
What do you mean by «retrieve»?
I don’t create pure Java API for metric intentionally.
We have MetricExporterSPI for this purpose.
It very simple from my point of view.
What use cases for `Ignite.monitoring()` API exists?
Agree with Alexey, there should be an obvious public API to retrieve metrics

This would provide the same value for the user as `IgniteMonitoring` you

I think it would make sense to make something like a new IgniteMonitoring
facade on Ignite interface and add an ability to obtain a metric value
through this facade, not through an exporter. This would be a
straightforward replacement for all old metrics interfaces.

Hello!
I have bumped beanutils and re-ran Cassandra Store tests. Can you please
comment on the ticket?
I think that fixing ZooKeeper is too much effort (there's chaos with
jackson vs. jackson-asl), maybe it should be split up as a separate ticket
to be done later.

Let's say I am upgrading from 2.7 to 2.8. Given that I figured out to

Alexey.
I think, yes.
We certainly should be able to use system view data for the new KILL API.
I think we should support both SQL and Java(JMX) API for this KILL command.

Nikolaj,
Can we use system views instead of implementing something new ?
Each user operation has an unique ID.
It's possible to introduce universal SQL kill something like:
kill transaction ID
where id is taken from system view.

Nikolaj,
We already have cancellation possibilities for almost every user
computation.
Transactions are cancelled using tx.rollback()
Queries are cancelled using query.close()
Task is cancellable through ComputeTaskSession
What is uniform cancel API ? Why do we need it ?

Alexey, if I understand correctly, Ilya does not suggest to pre-built
binaries, just to ship it with configure script pre-generated, which
is a common practice for autotools packages. Building will be still
required for the user, but there will be less requirements and
possible errors during build.
