Nikolay, reformulating doesn't make metrics more meaningful. Seriously :)

I don’t agree with you.
I believe they are not useless for a user.
And I try to explain why I think so.

How will it be visible?
For example, the user saw «checkpoint time» metric becomes x2 bigger.
How it relates to business operations? Is it become slower or faster?
What does it mean for an application performance?
On the other hand - if `PuTime` increas

I just quote your words: " this is a trigger to make a deeper
investigation". And if we have two metrics that are triggered for the
same then one of them is useless.

Anton,
Shouldn't we target IGNITE-12470 to 2.8? It kind of does not make sense to
add an ability to disable potentially dangerous change only in the next
release.

I don't understand what is the two metrics you are talking about.
I wrote about a single metric for a single cache operation.

Please, don't loose context. In your example it was checkpoint time
and some cache operation time.

We already have "something". put, get, etc. metrics. As I told early

Andrey,
I don't know why the issue [1] has an open status, but according to
release notes [2] and checkstyle-PR [3] the default behaviour for the
check `NewlineAtEndOfFile` has changed to `lf_cr_crlf` and works.
Actually, you may probably find a long interesting discussion in this
PR [3] about
Hello!
This module has two obvious downsides:
- It's LGPL.
- It can only schedule locally.
We could fix 1) by using other implementation, but given 2) this no longer
sounds feasible. If someone wants to use local scheduler, why not just use
it directly?

Can we use "autocrlf" safely? AFAIR there were problems (in other
project) with some Windows specific stuff if CRLF is replaced to LF
automatically.
