Sergey Uttsel commented on IGNITE-18624:
----------------------------------------
I make a PoC. When we replace BaselineManager#nodes with the data nodes from
DistributionZoneManager we will see a lot of flaky test.
This is because there is a delay between updating the data nodes in the
physical topology that the BaselineManager uses and the data nodes in the
DistributionZoneManager.
We need to investigate approach to solve these issue. We can update the tests
or create a general solution.
