Maybe i'll rename it to smth like setTieredLayout

[filimonov]

Failures - are minor (need to adjust the test for distributed plan)

[ianton-ru]

I can understand near 20% of code - that code is LGTM. :)

Test failures:

02210_processors_profile_log

https://altinity-build-artifacts.s3.amazonaws.com/json.html?PR=1071&sha=b28b8ed30ae3f637070e5063ff97a49cc47f11fe&name_0=PR&name_1=Stateless+tests+%28amd_binary%2C+ParallelReplicas%2C+s3+storage%2C+parallel%29&name_2=Tests

probably a timer accuracy issue (less than 20 microseconds of mistake)

Potential fix is smth like

tests/queries/0_stateless/02210_processors_profile_log.sql (+2 -1)
24             -- so it cannot starts to execute before sleep(1) will be executed.
25    -        input_wait_elapsed_us>=1e6 ? 1 : input_wait_elapsed_us)
25    +        -- CLOCK_MONOTONIC_COARSE may report slightly less than 1e6 us, so use same tolerance.
26    +        input_wait_elapsed_us>=0.99e6 ? 1 : input_wait_elapsed_us)
27         elapsed,

Unrelated.

Looks like a known issue (something with IPv6 stack?)
