Aleksey Plekhanov commented on IGNITE-13295:
--------------------------------------------
[~slava.koptilin], looks good to me. I've left one minor comment on github,
it's almost not related to your changes, but as far as you refactor the test, I
think it's better to remove redundant code in this test. But it's up to you,
fix it or keep as is.
